NK cell

NK cells are thought to be an important cell type in this process.

NK cell receptors can also be differentiated based on function.

NK cell activity and lymphocyte levels declined in the controls.

The NK cell is then able to kill these foreign pathogens.

Everyone knows this, but NK cells are the exception.

This inhibition is crucial to the role played by NK cells.

If the NK cells win, these symptoms abate and the patient lives.

They also had haematological defects and an increased NK cell number.

NK cells can also directly target the transplanted tissue.

A single NK cell can destroy up to 27 cancer cells before its lifespan.

The cell of origin is believed to be an NK cell.

NK cells, which lack antigen specific receptors, develop in the bone marrow.

B-lymphocytes, NK cells and cytokines also play a role in it.

NK cells secrete a high level of cytokines which help mediate their function.

This cytokine is also implicated in NK cell development.

NK cells are activated in response to interferons or macrophage-derived cytokines.

Cytokines play a crucial role in NK cell activation.

There was no significant difference in cytokine production, NK cell activity or other immune function parameters between the two groups.

Earlier it was thought that NK cells play no role in the adaptive immune responses, but now it seems they do.

For many years it was unclear how NK cell recognize tumor cells and infected cells.

So if these ligands are missing, there is no inhibitory signal and NK cell becomes activated.

The subtypes α10 and α2, along with α8, are the most efficient and powerful NK cell activators.

This would normally trigger NK cells by missing self recognition, however these cells survive.

It is the balance between these competing signals that determines whether or not the cytotoxic activity of the NK cell should get started.
