K cell

In between the six layers are smaller cells that receive information from the K cells (color) in the retina.

It is synthesized by K cells, which are found in the mucosa of the duodenum and the jejunum of the gastrointestinal tract.

Similar in physiology and connectivity to W cells in cat lateral geniculate nucleus, K cells form three pairs of layers in macaques.

As other scientists began to explore this phenomenon these lymphocytes came to be called "K cells" or "Killer cells" and were found to play a major role in immune response.

Gastric inhibitory polypeptide (GIP), also called glucose-dependent insulinotropic polypeptide, is a 42-amino acid polypeptide synthesized by K cells of the duodenum and small intestine.
