Evolving superantigens of Staphylococcus aureus.
Staphylococcus aureus bacteria utilize an extensive array of molecular countermeasures to manipulate the defensive microenvironment of the infected host and colonize potentially any tissue. The secreted polypeptides referred to as superantigens are unique among these countermeasures, because they target the multireceptor communication between T cells and antigen-presenting cells that is fundame...
متن کاملToll-Like Receptors, Their Ligands, and Atherosclerosis
Atherosclerosis is a disease characterized by inflammation in the arterial wall. Atherogenesis is dependent on the innate immune response involving activation of Toll-like receptors (TLRs) and the expression of inflammatory proteins. TLRs, which recognize various pathogen-associated molecular patterns, are expressed in various cell types within the atherosclerotic plaque. Microbial agents are a...
متن کاملToll-Like receptors (TLRs) and their ligands.
The innate immune system is an evolutionally conserved host defense mechanism against pathogens. Innate immune responses are initiated by pattern recognition receptors (PRRs), which recognize microbial components that are essential for the survival of the microorganism. PRRs are germline-encoded, nonclonal, and expressed constitutively in the host. Different PRRs react with specific ligands and...
متن کاملI-23: Reproduction and Toll Like Receptors(TLRs
Female and male reproductive tracts are of interest sites to study of immune system because they encounter specific infections such as those are sexually transmitted. Furthermore, female reproductive tract is in close contact with allogenic sperms and transmitted microorganisms during intercourse and semi allogenic fetus during pregnancy. In mammals, there are two types of immune responses, the...
متن کاملStaphylococcus aureus superantigens and their role in eosinophilic nasal polyp disease.
Nasal polyposis is a chronic disease of the upper airways which adversely affects the quality of life of patients. Its pathophysiology is still unclear. Recently, several studies have shown different inflammatory pathways which relate to both innate and adaptive immune responses. Moreover, different phenotypes may exist in different ethnic groups of patients. This article will review recent dat...
