(2013) targeted deletion of interferon regulatory factor 4 (Irf4) specifically in CD11c-expressing cells by means of the Cre-loxP system (Gao et al., 2013). Genetic deletion of Irf4 in DCs led to the absence of PD-L2hi CD301b+ (CD8α−) migratory DCs from the skin-draining lymph ...
Serial sections were immunolabeled for the integrins alpha(2)beta(1), alpha(v)beta(3), alpha(4)beta(1), alpha(L)beta(2) (CD11a), alpha(M)beta(2) (CD11b), and alpha(X)beta(2) (CD11c), and the ligands fibronectin, laminin, vitronectin, intercellular adhesion molecule-1, and ...
(high), CD2, CD26, CD38, CD94 (high), and HLADR (high, heterogeneous) antigens, and negative for surface CD3, TCR, CD4, CD5, CD7, CD8, CD11b, CD11c, CD16, CD56, CD57, and CD161, as well as for cytoplasmic CD3; in addition, they express intracellular granzyme B and perforin...
Producing a healthy immune system capable of defending against pathogens, while avoiding autoimmunity, is dependent on thymic selection. Positive selection yields functional T cells that have the potential to recognize both self and foreign antigens. Therefore, negative selection exists to manage potential...
