This natural killer cell
interacts with the CD94/ NKG2A receptor, part of a system believed to have been in place in humans for more than 90 million years.
When elderly subjects took 100 mg of Cistanche extract daily for 12 weeks, there was a 6.1% increase in helper T cells and an almost 12% increase in natural killer cell

Among the topics are a historical overview of immunological tolerance, dendritic cells as arbiters of immunity and immunological tolerance, natural killer cell
tolerance, the immunogenetic architecture of autoimmune disease, and current and future immunomodulation strategies to restore tolerance in autoimmune diseases.
The cell surface expression profile of the following activatory receptors was studied on NK cell population using flow cytometry: a low affinity receptor for aggregated IgG (CD16), members of NKG2 natural killer cell
receptor family (NKG2D/CD314 and NKG2C associating with CD94 to form a heterodimer), members of the natural cytotoxicity receptor (NCR) family (NCR1/NKp46, NCR2/NKp44, and NCR3/NKp30), a killer cell
immuno globulin-like receptor (KIR2DL4/CD158d), DNAX accessorymolecule-1 (DNAM-1/CD226), and lysosome-associated membrane protein-1 (LAMP1/CD107a).
Ig-like receptor (KIR) binds to HLA class I molecules on the surface of target cells, and it confers inhibitory signals to NK cells (25), (26).
