  • A complement receptor is a membrane-bound receptor belonging to the complement system, which is part of the innate immune system

    Complement receptors bind effector protein fragments that are produced in response to antigen-antibody complexes or damage-associated molecules. Complement receptor activation contributes to the regulation of inflammation, leukocyte extravasation, and phagocytosis; it also contributes to the adaptive immune response. Different complement receptors can participate in either the classical complement pathway, the alternative complement pathway, or both. Expression and function White blood cells, particularly monocytes and macrophages, express complement receptors on their surface.…

  • Complement receptor type 1 (CR1)

    Complement receptor type 1 (CR1) also known as C3b/C4b receptor or CD35 (cluster of differentiation 35) is a protein that in humans is encoded by the CR1 gene. This gene is a member of the regulators of complement activation (RCA) family and is located in the ‘cluster RCA’ region of chromosome 1. The gene encodes a monomeric single-pass type I membrane glycoprotein found on erythrocytes, leukocytes, glomerular podocytes, hyalocytes, and splenic follicular dendritic…

  • Melanin-concentrating hormone (MCH) aka PMCH

    Melanin-concentrating hormone (MCH), also known as pro-melanin stimulating hormone (PMCH), is a cyclic 19-amino acid orexigenic hypothalamicpeptide originally isolated from the pituitary gland of teleost fish, where it controls skin pigmentation. Barson JR, Morganstern I, Leibowitz SF (2013). “Complementary roles of orexin and melanin-concentrating hormone in feeding behavior”. International Journal of Endocrinology. 2013: 983964. doi:10.1155/2013/983964. PMC 3727095. PMID 23935621. In mammals it is involved in the regulation of feeding behavior, mood,…
