Macrophage Receptors for Bacterial Cell-wall Sugars and Immune Response Genes: Possible Determinants of Susceptibility to Infection
| Abstract |
|---|
Recognition of bacteria, antigen presentation and regulation of the immune response by the class II antigens of the major histocompatibility complex (MHC) are among the many factors that influence a host's response to microbial infection Lectin-like receptors on the macrophage membrane recognize a variety of bacteria by interaction with their cell-wall sugars. These receptors are susceptible to environmental factors and appear to be associated with the I-A subregion of the mouse MHC. Possible effects of this recognition system on the pathogenesis of microbial infection and reactive arthntides are considered.
