Sentinel cell - Wikipedia

Sentinel cells refer to cells in the body's first line of defense, which embed themselves in tissues such as skin. Sentinel cells can refer to specific antigen-presenting cells, such as: . Macrophages. Kupffer cells - in the liver; Langerhans cells - in the skin and mucosa (*these are a form of dendritic cells); Alveolar macrophages - in the lungs; Microglia - in the brain

Assessment of the Tissue Resident Memory Cells in Lesional ...

Background: In the course of plaque psoriasis, tissue resident memory cells (TRM) are responsible for the phenomenon of "immune memory" of lesions, i.e., the appearance of recurrences of lesions in the same location, as well as Koebner phenomenon. We present results determining the location and amount of TRM in psoriatic lesions in patients suffering from …

Nerves: The Histology Guide

Supporting cells in the central nervous system. In the central nervous system, there are four types of supporting cells.. 1. Oligodendrocytes. The axons of many neurons are insulated by a myelin sheath, which increases the rate at which an axon can conduct an action potential. In multiple sclerosis, the myelin sheaths in the CNS are destroyed, and action potentials are slowed.
