Naïve cells are non-active lymphocytes that recognize and bind to specific antigens, become activated, and launch target attacks against foreign pathogens.
Two phenotypically distinct populations can be distinguished based on the expresssion of the WC1 antigen. The mechanisms responsible for the activation of these cells remain obscure. To address this question we have developed an in vitro model in which purified WC1 γ/δ T cells (CD2~-, CD3~...
NK1.1+CD4+ T cells lose NK1.1 expression upon in vitro activation. J. Immunol. 158, 5112–5119 (1997). CAS PubMed Google Scholar Eberl, G. & Macdonald, H. R. Rapid death and regeneration of NKT cells in anti-CD3-ε- or IL-12-treated mice — a major role for bone marrow in ...
These cells may be involved in the pathogenesis of IBD by secreting interferon γ and enhancing the differentiation of Th1 cells from naive CD4+T cells. In addition, excessive amount of interferon γ has destructive effects on the tight junctions of the intestinal mucosal barrier [40], which is...
One side of a BiTE is designed to bind to CD3 and activate T cells, while the other side is directed against a tumor antigen. The combination with BiTEs allows CAR-T cells to aim at distinct antigens by altering BiTEs. This concept has been tested in preclinical models to avoid antigen ...
Currently, the diagnoses of MF and SzS rely on the identification of specific (bio)markers that distinguish these diseases from other skin conditions. The identification of Sézary cells based on the detection of the monoclonal cells of the following phenotype: CD2+, CD3+, CD4+ CD5+, CD7−...

CTAs are a class of antigens not typically expressed by normal cells outside of the testes—cells of which do not express MHC class I, nor present antigens to CD8+ T cells. However, CTAs are frequently expressed on cancer cells.30 Human CTAs, such as synovial sarcoma X-2 (SSX-2), ...
A high degree of suspicion coupled with morphologic and IHC analysis showing positive CD5, CD20, and cyclin D1 and negative CD23 and CD3 can guide us to the diagnosis of MCL. Coexisting mantle cell lymphoma and prostate adenocarcinoma Mouse beta cells express all three D cyclins, D1, D2,...
