Clin Immunol ; 1: Following their development in the thymus, a major fraction of iNKT cells stays there and the rest migrate to peripheral sites, where they make up a relevant T-cell subset in the bone marrow, spleen, blood and liver, being less common in lymph nodes J Exp Med ; 4: Among these, intracellular lipids from apoptotic enterocytes released during inflammation, dietary glycolipids modified by non-physiological enzymes, and glycolipids from bacteria within the intestinal lumen stand out.

However, under normal conditions, eosinophils are commonly seen in the intestinal mucosa and authors such as Svenson-Frej et al. Emerging insights in development, lineage relationships, and function.


Furthermore, uncontrolled or inadequate NKT-cell activation may contribute to the pathogenesis of intestinal inflammatory diseases Nat Immunol ;12 7: Therefore, DCs represent a nexus between innate non-antigen-specific immune response and the highly specialized adaptive immune response.

J Clin Invest ; 5: Linfoma primario asociado a efusiones: Interestingly, iNKT cells are less common in most human versus murine organs, and their prevalence varies greatly between subjects because of yet unknown reasons Immunology and Cell Biology ;91 3: In contrast to conventional T cells, which recognize peptides bound by crlulas histocompatibility complex MHC class I or class II molecules, NKT cells celulaz lipidic and glycolipidic structures bound by CD1d molecules Intrasinusoidal bone marrow infiltration: Exogenous and endogenous glycolipid antigens activate NKT cells during microbial infections.

Given the significance of iNKT cells for immune response initiation and regulation, these results may also help in understanding the increased incidence of both infections and malignancies, as well as the increased celulws of autoimmune conditions, in the elderly 76, It also includes a great variety of lymphoid cells in the lamina propria LPand intraepithelial effector lymphocytes IELs interspersed in the epithelial lining 2.
