The human mannose-binding protein functions as an opsonin
The human mannose-binding protein (MBP) is a multimeric serum protein that is divided into three domains: a cysteine-rich NH2-terminal domain that stabilizes the alpha-helix of the second collagen-like domain, and a third COOH-terminal carbohydrate binding region. The function of MBP is unknown, although a role in host defense is suggested by its ability to bind yeast mannans. In this report we...
متن کاملHuman Mannose-binding Protein Functions
Influenza A viruses (IAVs) cause substantial morbidity and mortality in yearly epidemics, which result from the ability of the virus to alter the antigenicity of its envelope proteins. Despite the rapid replication of this virus and its ability to infect a wide variety of cell types, viremia is rare and the infection is generally limited to the upper respiratory tract. The preimmune host defens...
متن کاملThe sea urchin complement homologue, SpC3, functions as an opsonin.
The purple sea urchin Strongylocentrotus purpuratus expresses a homologue of complement component C3 (SpC3), which acts as a humoral opsonin. Significantly increased phagocytic activity was evident when yeast target cells were opsonized after incubation with coelomic fluid containing SpC3. SpC3 could be detected on the surface of yeast, and phagocytic activity could be inhibited by an anti-SpC3...
متن کاملThe Human Mannose-binding Protein Gene
The human mannose-binding protein (MBP)' is an acute phase serum protein of -300 kD comprised of multimers of a 32-kD subunit (1-3). It is a member of an ever-growing family of animal lectins that share at least 18 invariant residues in their carbohydrate recognition domain (CRD). The family can be divided into membrane proteins and soluble proteins, and all bind ligands optimally at neutral pH...

Background: Interleukin8 (IL-8) realized from keratinocytes in the presence of dermatophytic antigens causesinduction of acute responses in dermatophyte infection and subsequently production of acute phaseproteins occurs in hepatocytes. C–reactive protein (CRP) and Mannose–binding lectin (MBL) areacute phase proteins. Since few researches in the case of acute phase proteins in dermatophyticinfe...
