Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cosmetic efficacy evaluation, and in particular to a method for evaluating and improving skin inflammation and aging based on a zebrafish model and its application. Background Art
[0002] In skin inflammatory aging, inflammation and aging are mutually causal. When the skin is exposed to stressors for a long time, the dynamic balance between pro-inflammatory and anti-inflammatory is broken, leaving the skin in a state of chronic inflammation. Chronic inflammation leads to skin cell aging (such as DNA damage, telomere shortening, oxidative stress, etc.), which in turn accelerates the skin aging process. Aging skin cells secrete senescence-associated secretory phenotypes (SASPs), such as proinflammatory factors, chemokines, and matrix metalloproteinases, which change the skin microenvironment, affect the state of surrounding healthy cells, lead to DNA breakage and oxidative stress damage, and ultimately form a vicious cycle of inflammatory aging.
[0003] Repeated overexposure to UV radiation induces skin aging, a process that shares many similarities with natural aging. UV rays, particularly UVB, damage the DNA and protein structure of skin cells, leading to cellular aging. They also induce keratinocytes, dermal fibroblasts, and mast cells to secrete proinflammatory cytokines, triggering an inflammatory cascade in the skin. This creates a vicious cycle of inflammation and aging, ultimately leading to aging symptoms such as epidermal atrophy, delayed wound healing, and sagging.
[0004] Neutrophils are one of the most important innate immune cells involved in inflammatory responses. Activated by inflammatory stimuli, neutrophils migrate to inflamed areas of the skin under the influence of a gradient of soluble chemokines. They eliminate inflammation through phagocytosis, degranulation, and the production of reactive oxygen species and extracellular traps, thereby restoring homeostasis and promoting skin repair. If inflammation is not well regulated, persistent eosinophilic inflammation can cause skin tissue damage and chronic inflammation, leading to inflammatory aging of the skin and the appearance of aging phenotypes (such as wrinkles).
[0005] Existing inflammatory aging models are primarily cellular models. Single-cell models struggle to simulate the interactions between cells in vivo and fail to reflect true inflammatory responses in vivo. Zebrafish, a small vertebrate model organism, and transgenic zebrafish with labeled neutrophils provide a valuable tool for studying inflammatory responses in vivo. Their transparent larvae, small size, and robust reproductive capacity complement the shortcomings of traditional in vitro evaluation models, effectively reducing experimental costs and shortening experimental cycles while providing intuitive and easily interpretable results. Summary of the Invention
[0006] In vivo, UVB can activate neutrophils through the cell signal transduction system. Under the action of soluble chemokines, neutrophils are recruited to the skin inflammation reaction site, and participate in the intracellular inflammatory reaction process, remove related pathogens, and play an immunomodulatory role. Excessive UVB makes it difficult to effectively control inflammation. Sustained eosinophilic inflammation causes skin tissue damage and chronic inflammation, which then triggers skin inflammation and aging. Zebrafish, as a model organism, has a high genetic homology and skin structure similarity with humans, and this phenomenon is also present in its body. Therefore, the present invention uses zebrafish to establish a method for evaluating and improving skin inflammation and aging.
[0007] In a first aspect, the present invention provides a method for evaluating and improving skin inflammation and aging based on a zebrafish model, comprising the following steps:
[0008] Step S1, selecting several zebrafish with the same tail development status and not treating them to establish a blank group;
[0009] Step S2, selecting the same number of zebrafish with the same developmental status as in step S1, stimulating the zebrafish with UVB to establish a model group;
[0010] Step S3, selecting the same number of zebrafish as in step S1 and with the same developmental status, adding the test sample, and stimulating the zebrafish with UVB to establish a sample group;
[0011] Step S4, incubating the blank group, model group, and sample group under the same conditions for 16 h to 20 h;
[0012] Step S5, observing the zebrafish in the blank group, model group, and sample group under a stereo fluorescence microscope, and recording the anti-inflammatory efficiency and anti-wrinkle efficiency of the zebrafish;
[0013] Step S6: Evaluate the efficacy of the sample in improving skin inflammation and aging according to the anti-inflammatory aging calculation formula.
[0014] In the aforementioned zebrafish model-based evaluation of methods for improving skin inflammation and aging, the zebrafish used were 36-48 hpf (hpf) zebrafish Tg (mpx:dsRED) with red fluorescently labeled neutrophils. This zebrafish strain has a well-defined genome, high commercial availability, and stable embryo quality, which improves the stability of experimental results. Zebrafish neutrophils are generated from myeloid precursor cells and hematopoietic stem cells. The first mature neutrophils can be detected at 35 hpf, and all neutrophils are mature by 48 hpf. Zebrafish at 48 hpf are not yet capable of swimming, and UVB stimulation is more evenly distributed across the sides of the fish, resulting in a more uniform and stable modeling effect. Therefore, zebrafish Tg (mpx:dsRED) with red fluorescently labeled neutrophils at 36-48 hpf can be used as test organisms in this method.
[0015] In the above-mentioned zebrafish model-based method for evaluating the improvement of skin inflammation and aging, in steps S2 and S3, the UVB dose is 72mJ / cm 2 ~81mJ / cm 2 72mJ / cm 2 ~81mJ / cm 2 UVB stimulation caused neutrophils to migrate to the zebrafish skin and recruit to the inflamed areas. The inflammation was difficult to subside, resulting in a chronic inflammatory state in the zebrafish skin, which then triggered inflammatory aging of the skin. Specifically, the skin of the zebrafish caudal and dorsal fins showed obvious wrinkling and a large number of neutrophils were recruited to the wrinkles. This dose range was selected for the inflammatory aging model test. The fluorescence area of the zebrafish caudal and dorsal fins increased, while the caudal and dorsal fin areas decreased in the blank and model groups. The relevant data showed significant differences, indicating that the inflammatory aging model was successfully established.
[0016] In the above-mentioned method for evaluating and improving skin inflammation and aging based on the zebrafish model, in step S2, the criteria for successfully establishing the model group are: compared with the blank group, the fluorescent area of the caudal fin and dorsal fin of the model group increased, and the area of the caudal fin and dorsal fin decreased; at the same time, the statistical data of the fluorescent area of the caudal fin and dorsal fin of the blank group and the model group and the area of the caudal fin and dorsal fin of the blank group and the model group were all less than 0.05 after variance analysis.
[0017] In the above method for evaluating the improvement of skin inflammation and aging based on the zebrafish model, in step S5, the anti-inflammatory efficiency R 抗炎 The observed indicator is the recruitment of neutrophils in the caudal fin and dorsal fin of zebrafish, that is, the fluorescent area of the caudal fin and dorsal fin, and the calculation formula is as follows:
[0018]
[0019] Among them, S 样品组 is the average fluorescence area of the caudal fin and dorsal fin of zebrafish in the sample group; S 模型组 is the average fluorescence area of the caudal fin and dorsal fin of the model group; S 空白组 is the average fluorescence area of the caudal fin and dorsal fin of the blank group.
[0020] In the above method for evaluating the improvement of skin inflammation and aging based on the zebrafish model, in step S5, the anti-wrinkle efficiency R 抗皱 The observation indicators are the areas of the zebrafish tail fin and dorsal fin, and the calculation formula is as follows:
[0021]
[0022] Among them, S 样品组 is the average area of the caudal fin and dorsal fin of the zebrafish in the sample group; S 模型组is the average area of the caudal fin and dorsal fin of the model group; S 空白组 is the average area of the caudal fin and dorsal fin of the blank group.
[0023] In the above-mentioned method for evaluating and improving skin inflammation and aging based on the zebrafish model, in step S6, the anti-inflammatory aging calculation formula is:
[0024] R 抗炎症衰老 =0.4287*R 抗皱 +0.6315*R 抗炎 -1.368.
[0025] In a second aspect, the present invention provides the application of the above-mentioned method for evaluating the improvement of skin inflammation and aging based on the zebrafish model in screening raw materials for cosmetics with efficacy in improving skin inflammation and aging.
[0026] Compared with the prior art, the present invention has at least the following beneficial effects:
[0027] Most existing technologies use inflammatory aging cell models, which primarily evaluate the efficacy of samples in improving inflammatory aging at the molecular and cellular levels. These models are unable to simulate the interactions between cells in an organism and provide feedback on the true efficacy of the sample being tested. The present invention accurately grades the efficacy of cosmetic raw materials in improving skin inflammatory aging at the whole animal level, addressing the shortcomings of the existing technology. Furthermore, the present invention features simple operation, low cost, good reproducibility, and a high degree of visualization. It creatively uses a binary linear fitting equation to calculate the anti-inflammatory aging efficiency of a sample, which can simply and intuitively reflect the efficacy of cosmetic raw materials in improving skin inflammatory aging, providing scientific and intuitive data support for related product development by companies.

[0054]
[0055] like Figure 2 As shown, the area within the dotted line is the area of the zebrafish tail fin and dorsal fin ( Figure 2 Left), caudal fin and dorsal fin fluorescence area ( Figure 2 Right) statistical area. Combined Figure 3 and Figure 4 Compared with the blank control group, the caudal and dorsal fins of zebrafish in the model group showed significant wrinkling, and a large number of neutrophils were recruited to the wrinkled areas. Compared with the blank control group, the fluorescent area of the caudal and dorsal fins in the model group increased, while the caudal and dorsal fin areas decreased. The data were analyzed by variance analysis with p values less than 0.05, indicating that the inflammatory aging model was successfully established.
[0056] Compared with the model group, sample 1R 抗炎 >0% and p<0.05, indicating that sample 1 has anti-inflammatory effect; R 抗 Wrinkle < 0% and p > 0.05, indicating that the aging state of sample 1 is consistent with that of the model group and has no anti-wrinkle effect. From the phenotypic results, it can be seen that the degree of wrinkling of the tail fin and dorsal fin of sample 1 is similar to that of the model group, and neutrophils disappear in the wrinkled areas, indicating that sample 1 has a certain effect on improving skin inflammation and aging, which is consistent with R 抗炎症衰老 The calculated result is 25.78%.
[0057] Compared with the model group, sample 2R 抗炎 >0% and p<0.05, indicating that sample 2 has anti-inflammatory effect; R 抗Wrinkle>0% and p<0.05, indicating that sample 2 has an anti-wrinkle effect. From the phenotypic results, it can be seen that compared with the model group, the wrinkles of the tail fin and dorsal fin of sample 2 are less severe, and neutrophils show a significant disappearance in the wrinkled areas, indicating that sample 2 has a good effect in improving skin inflammation and aging, which is consistent with R 抗炎症衰老 The calculated results are consistent with 48.78%.
[0058] Compared with the model group, sample 3R 抗炎 >0% and p<0.05, indicating that sample 3 has anti-inflammatory effect; R 抗 Wrinkle>0% and p<0.05, indicating that sample 3 has an anti-wrinkle effect. From the phenotypic results, it can be seen that compared with the model group, the tail fin and dorsal fin of sample 3 zebrafish basically did not show wrinkles, and neutrophils appeared and significantly subsided in the tail fin and dorsal fin, indicating that sample 3 has a very good effect in improving skin inflammation and aging, which is consistent with R 抗炎症衰老 The calculated results are consistent with 102.45%.
[0059] Compared with the model group, sample 4R 抗炎 <0% and p < 0.05, indicating that sample 4 has a pro-inflammatory effect; R 抗 Wrinkle < 0% and p > 0.05, indicating that the aging state of sample 4 is consistent with that of the model group and has no anti-wrinkle effect. From the phenotypic results, it can be seen that compared with the model group, the degree of wrinkling of the tail fin and dorsal fin of sample 4 is similar to that of the model group, and neutrophils are more obviously recruited at the wrinkled areas, indicating that sample 4 has no effect on improving skin inflammation and aging, and has a pro-inflammatory effect, which is consistent with R 抗炎症衰老 The calculated result is -41.22%.
[0060] Compared with the model group, sample 5R 抗炎 >0% and p<0.05, indicating that sample 5 has anti-inflammatory effect; R 抗 Wrinkle>0% and p<0.05, indicating that sample 5 has an anti-wrinkle effect. From the phenotypic results, it can be seen that compared with the model group, the wrinkle degree of the zebrafish tail fin and dorsal fin in sample 5 was significantly reduced, and the neutrophils showed a significant disappearance in the wrinkled area, indicating that sample 5 has a good effect on improving skin inflammation and aging, which is consistent with R 抗炎症衰老 The calculated results are consistent with 64.24%.
[0061] Compared with the model group, sample 6R 抗炎 >0% and p<0.05, indicating that sample 6 has anti-inflammatory effect; R 抗 Wrinkle>0% and p>0.05, indicating that the aging state of sample 6 is consistent with that of the model group and has no anti-wrinkle effect. From the phenotypic results, it can be seen that compared with the model group, the degree of wrinkling of the tail fin and dorsal fin of sample 6 is similar to that of the model group, and neutrophils disappear in the wrinkled areas, indicating that sample 6 has a certain effect on improving skin inflammation and aging, which is consistent with R 抗炎症衰老The calculated result is 29.41%.
[0062] Comparative Example 1
[0063] The difference between Comparative Example 1 and Example 1 is that the UVB dose is 54mJ / cm 2 , the rest of the steps are exactly the same.
[0064] pass Figure 5 、 Figure 6 It can be seen that in Comparative Example 1, compared with the blank group, the fluorescent area of the caudal fin and dorsal fin of the model group increased slightly, and the data were analyzed by variance analysis p < 0.05; the caudal fin and dorsal fin area decreased slightly, but the data were analyzed by variance analysis p = 0.1915 > 0.05. At the same time, compared with the model group in Example 1, the number of neutrophils in the caudal fin and dorsal fin wrinkles of Comparative Example 1 decreased significantly. The above results show that when the UVB dose is 54mJ / cm 2 Although neutrophils can be activated to migrate to the zebrafish skin, the inflammatory response is easy to subside and the skin damage is easy to repair, which cannot cause skin inflammation and aging, and ultimately leads to model failure. It is not suitable as a modeling dose.
[0065] Comparative Example 2
[0066] The difference between Comparative Example 2 and Example 1 is that the UVB dose is 108 mJ / cm 2 , the rest of the steps are exactly the same.
[0067] When the UVB dose is 108mJ / cm 2 The mortality rate of the model group was 53%, and subsequent efficacy evaluation was not possible. 2 When the dose is too high, it causes irreparable damage to the zebrafish and is not suitable as a modeling dose.
[0068] In summary, the present invention provides a method for evaluating and improving skin inflammation and aging based on a zebrafish model and its application, which accurately grades the efficacy of cosmetic raw materials in improving skin inflammation and aging based on the whole animal level. Different from traditional test models, the present invention is simple to operate, low in cost, reproducible, and highly visualized. It creatively uses a binary linear fitting equation to calculate the anti-inflammatory and aging efficiency of the sample, which can simply and intuitively reflect the efficacy of cosmetic raw materials in improving skin inflammation and aging, and provide scientific and intuitive data support for the development of related products of enterprises.
