The application belongs to the technical field of biological medicine, and discloses a cyclic peptide molecule specifically targeting CD5 and purposes thereof. The surface receptor CD5 of immune cells (T cells, B cells) has been proved to be a potential tumor treatment target, the present application uses the phage display technology widely applied to the development of polypeptide or antibody drugs to carry out multiple rounds of in vitro screening on human CD5 protein, and obtains a cyclic peptide molecule with drug potential and capable of specifically combining with CD5 through second-generation sequencing. The cyclic peptide molecule contains two cysteines, is modified into a ring through a specific chemical crosslinking agent, and the affinity of the cyclic peptide molecule to CD5 is determined to be in the low micromolar level through surface plasmon resonance technology, thereby laying a foundation for the development of a CD5-targeting inhibitor.

The invention relates to the technical field of biomedicine, in particular to an immunoregulation chiral material as well as a preparation method and application thereof, and the immunoregulation chiral material is formed by self-assembly of an immune active component and a delivery carrier. The immunocompetence component is selected from chiral peptide modified distearoyl phosphatidyl ethanolamine-polyethylene glycol, and the chiral peptide is formed by connecting 6-10 D-alanine monomers through amido bonds. The material can realize accurate targeting on target cells by virtue of specific three-dimensional recognition of chiral peptides and immune cell surface receptors, and reduces non-specific action on normal tissues; a delivery carrier represented by lipid nanoparticles can effectively protect chiral peptides from in-vivo enzymolysis and improve the cycling stability of the chiral peptides, and natural carriers such as exosomes can enhance the biocompatibility and tissue penetrability of the material, so that a new strategy is provided for immunotherapy of diseases such as tumors and the like; the compound is expected to be applied to clinical treatment as a novel immunotherapy drug.

The invention discloses an epigenetics method for improving the cryopreservation efficiency of sheep semen. The method comprises the following steps: extracting seminal fluid of Donflilien and Hu sheep hybrid F1-generation sheep, dividing the seminal fluid into a fresh group and a frozen group, carrying out somatic cell removal and small non-coding RNA extraction, screening out differentially expressed microRNAs by utilizing a Pandorah sequencing technology, analyzing a target gene and a signal channel of the microRNAs, and determining the seminal fluid of the Donflilien and Hu sheep hybrid F1-generation sheep. The small non-coding RNA related to sperm cryopreservation is found to mainly relate to key biological processes such as oxidative stress response and cell surface receptor signal channels. The screened differentially expressed small non-coding RNA is added into the frozen semen through methods such as in vitro chemical synthesis, so that the artificial fertilization conception rate of the frozen semen is remarkably increased.
