132 results about "Immunodeficiency" patented technology

Immunodeficiency is a state in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. Most cases of immunodeficiency are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection, extremes of age, and environmental factors, such as nutrition. In the clinical setting, the immunosuppression by some drugs, such as steroids, can be either an adverse effect or the intended purpose of the treatment. Examples of such use is in organ transplant surgery as an anti-rejection measure and in patients suffering from an overactive immune system, as in autoimmune diseases. Some people are born with intrinsic defects in their immune system, or primary immunodeficiency. A person who has an immunodeficiency of any kind is said to be immunocompromised. An immunocompromised person may be particularly vulnerable to opportunistic infections, in addition to normal infections that could affect everyone. Immunodeficiency also decreases cancer immunosurveillance, in which the immune system scans the body's cells and kills neoplastic ones.

Application of vitamin K3 in preparation of medicine for treating psoriasis

The invention belongs to the technical field of biological medicines, and discloses application of vitamin K3 in preparation of a medicine for treating psoriasis. The invention finds that the compound vitamin K3 can obviously inhibit the activation of the STING downstream immune pathway and has an inhibition effect on the activation of the STING pathway. A mouse psoriasis model is formulated according to the absorption and metabolism characteristics of the inhibitor VK3, and it is proved that the VK3 can significantly inhibit the process of psoriasis and up-regulation of an STING pathway at an affected part in a transdermal drug delivery mode. The STING pathway does not belong to a main pathway affecting the course of disease in most non-immunodeficient inflammatory diseases, so that a better treatment effect may be generated by using the STING pathway in combination with a direct treatment drug (such as an IL-17A antibody for psoriasis). The vitamin K3 is simple in chemical structure, mature in production process and low in preparation cost, has more remarkable price advantage compared with biological agents and small-molecule targeting drugs, and has high popularization value and application prospects.
