NK cells
29 November 2007Natural killer (NK) cells express cell surface receptors that recognize major histocompatibility complex class I peptides (MIM.142800) and inhibit NK cell-mediated cytotoxicity.
NK cell receptors belong to 2 distinct groups: the immunoglobulin superfamily for the killer cell inhibitory receptors (KIRs) (MIM.602992), and the C-type lectin superfamily for the NKG2 receptors (MIM.161555).
These inhibitory receptors possess ’immunoreceptor tyrosine-based inhibitory motifs’ (ITIMs) in their (...) -

Paneth cell differentiation in colonic epithelial tumors
Paneth cell differentiation may occur in colonic epithelial neoplasms.
Paneth cell differentiation is common in early colonic neoplasms that develop via the conventional adenoma-carcinoma carcinogenic pathway.
Activation of Apc/beta-catenin/Tcf pathway may play a role (...) -

Osteoprogenitor cells
Osteoprogenitor cells are pluripotent mesenchymal stem cells that are located in the vicinity of all bony surfaces.
When appropriately stimulated by growth factors such as bone morphogenic proteins, which are members of the TGF-β superfamily, they undergo cell division and produce offspring that differentiate into osteoblasts.
The process of osteoblastic differentiation is initiated and governed by the transcription factor core binding factor a1, which (...) -
