Toll-like receptors in the pathogenesis of human B cell malignancies
نویسندگان
چکیده
Toll-like receptors (TLRs) are important players in B-cell activation, maturation and memory and may be involved in the pathogenesis of B-cell lymphomas. Accumulating studies show differential expression in this heterogeneous group of cancers. Stimulation with TLR specific ligands, or agonists of their ligands, leads to aberrant responses in the malignant B-cells. According to current data, TLRs can be implicated in malignant transformation, tumor progression and immune evasion processes. Most of the studies focused on multiple myeloma and chronic lymphocytic leukemia, but in the last decade the putative role of TLRs in other types of B-cell lymphomas has gained much interest. The aim of this review is to discuss recent findings on the role of TLRs in normal B cell functioning and their role in the pathogenesis of B-cell malignancies.

External exposed radiation may play an important role in pathogens of irritable bowel syndrome (IBS), although is thought to arise due to a combination of genetic and environmental factors. The result is dysregulated immune responses due to alteration in the gut microbiota population and the subsequent development of gut inflammation. It has recently been shown that the effect of ioni...

Background: Toll like receptors (TLRs) are a major family of innate immune systems which recognize specific pathogen associated molecular patterns (PAMPS)in bacterial, fungi, virus and parasites. Human TLRs comprise a large family of 10 different type proteins that are expressed on various immune cells. Among these receptors, TLR1, 2, 4, 5, 6 and 10 were expressed on the cell surface. TLR2 form...

Background: Male infertility refers to the inability of a male to achieve a pregnancy in a fertile female. The root of many causes of infertility is miscommunication between immune and reproductive system. Male reproductive system is very sensitive and vulnerable, infections can hinder maturation and movement of spermatozoa lead to impaired fertility.All species need an immediate reply to the m...

P-33: Expression of Toll-Like Receptor 2-3 Genes in Human Sertoli Cells
Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...
