The immune system has crucial roles in the pathogenesis of multiple sclerosis. While the adaptive immune cell subsets, T and B cells, have been the main focus of immunological research in multiple sclerosis, it is now important to realize that the innate immune system also has a key involvement in regulating autoimmune responses in the central nervous system. Natural killer cells are innate lym...
Dasatinib, a dual tyrosine kinase inhibitor, is known to modulate or suppress T-cell activation and proliferation. We report a series of 8 patients who developed chronic peripheral lymphocytosis, identified as natural killer cells or natural killer/T-cells based on their large granular lymphocyte morphologies and CD16(+), CD56(+), CD3(-) or CD3(+) immunophenotypic profiles, out of 18 patients r...
Nasal type natural killer/T-cell lymphoma (NNKTL) is a rare and aggressive subtype of non-Hodgkin originating from killer cell or γδ T infected by the Epstein-Barr virus. It usually invades aerodigestive tract can rapidly destroy paranasal sinus, hard palate, central nervous system. NNKTL often mistaken for benign conditions such as chronic hypertrophic rhinosinusitis mucosal inflammatory chang...
Natural killer (NK) cells are a crucial part of the innate immune system and play critical roles in host anti-viral, anti-microbial, and antitumor responses. The elucidation of NK cell biology and their therapeutic use are actively being pursued with 200 clinical trials currently underway. In this review, we outline the role of NK cells in cancer immunotherapies and summarize current noninvasiv...
background: alteration in peripheral blood lymphocytes (pbls) is usually investigated to provide an evidence of the host immune responses to tumor antigens. the tumor infiltrating nk cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. objective: to analyze peripheral blood and tumor associated natural killer (nk) cells in patients with breast ca...
Last decade has seen a significant advancement in our understanding of the Natural Killer (NK) cell biology and function. Several receptors present on NK cells have been identified, which are involved in either their activation or inhibition. Similarly, a large number of interacting ligands have been identified on the target cells that upon interaction transmit either activating or inhibitory s...
