Natural Killer Cells in Asthma
The worldwide prevalence, morbidity, and mortality of asthma have dramatically increased over the last few decades and there is a clear need to identify new effective therapeutic and prophylactic strategies. Despite high numbers of NK cells in the lung and their ability to generate a variety of immunomodulatory mediators, the potential of NK cells as therapeutic targets in allergic airway disea...
متن کاملInvariant Natural Killer T Cells
Invariant Natural killer T cell (iNKT cells) are a subset of T cells, which are narrowly defined as a T cell lineage expressing a semi-invariant CD1d-restricted T cell Receptors (TCRs) composed by Vα24-Jα18/Vβ11 in human, and Vα14-Jα18/Vβ8,Vβ7, and Vβ2 in mouse. Unlike conventional T cells which recognize peptides bound to highly polymorphic major histocompatibility complex (MHC) class I and II...
متن کاملComparison of Two Flow Cytometric Methods for Detection of Human Invariant Natural Killer T Cells (iNKT)
Background: Invariant natural killer cells (iNKT) are an important immunoregulatory T cell subset. Currently several flow cytometry-based approaches exist for the identifi-cation of iNKT cells, which rely on using the 6B11 monoclonal antibody or a combina-tion of anti-Vα24 and anti-Vβ11 antibodies. Objective: The aim of this study was to compare the ability of two flow cytometry-based methods f...
متن کاملCD4+ invariant T-cell-receptor+ natural killer T cells in bronchial asthma.
BACKGROUND Bronchial asthma is associated with an inflammatory process that is characterized by the presence in the airways of large numbers of CD4+ T cells producing interleukin-4 and interleukin-13. However, the CD4 antigen is expressed not only by class II major histocompatibility complex (MHC)-restricted CD4+ T cells, but also by a newly identified subgroup of T cells, CD1d-restricted natur...
متن کاملinterleukin-12 and peripheral blood invariant natural killer t cells as an axis in childhood asthma pathogenesis
interleukin-12 (il-12) is a key cytokine involved in regulating the balance between th1 and th2 cells by promoting th1 response. a reduced capacity to produce this cytokine could lead to aberrant th2 development. on the same aspect significant impact of il-12 on invariant natural killer t (inkt) cells was reported. therefore, we examined the serum levels of il-12 and the absolute number of peri...
