IV. Tissue-resident NK (trNK) Cells. In the liver, a population of NK cells appeared to be similar to immature cNK cells because they express similar surface markers such as NK1.1 and NKp46 and low levels of CD11b [3, 6, 8].Moreover, they are DX5 − and display high levels of TNF-related apoptosis-inducing ligand (TRAIL). This immature phenotype gave the impression that organs such as the ...

Natural killer (NK) cells belong to the innate immune system; they can control virus infections and developing tumors by cytotoxicity and producing inflammatory cytokines. Most studies of mouse NK cells, however, have focused on conventional NK (cNK) cells in the spleen. Recently, we described two populations of liver NK cells, tissue-resident NK (trNK) cells and those resembling splenic cNK ...

Differentiation and diversity of subsets in group 1 innate ...

Different subsets of NK cells and ILC1 are found in different tissues in the body, giving rise to populations that either circulate in the body between compartments (mobile circulating) or do not transition between the blood and tissues, remaining predominantly ‘tissue-resident’.

JCI - NK cells in the tumor microenvironment and ...

Sep 14, 2020·Studies of tissue-resident NK (trNK) cells reveal the existence of phenotypic and functional heterogeneity that far exceeds the immune surveillance role originally attributed to NK cells. Environmental factors and/or epigenetic modifications of NK cell genes via DNA methylation may shape trNK cell functional diversity ( 7 ).

11 Different Types of Cells in the Human Body

Nov 13, 2019·Cells in the human body number in the trillions and come in all shapes and sizes. These tiny structures are the basic unit of living organisms. Cells comprise tissues, tissues make up organs, organs form organ systems, and organ systems work together to create an organism and keep it alive.. Each type of cell in the human body is specially equipped for its role.

Human Circulating and Tissue-Resident CD56(bright) Natural ...

However, CD56(bright) NK cells outnumber CD56(dim) NK cells in the human body due to the fact that they are predominant in peripheral and lymphoid tissues. Interestingly, within the total CD56(bright) NK cell compartment, a major phenotypical and functional diversity is observed, as demonstrated by the discovery of tissue-resident CD56(bright ...
