Why are these cells called memory NK cells? The classical definition of memory states that immune cells can “remember” a previous encounter with a pathogen and can therefore react faster and stronger in a second encounter with the same pathogen. Memory cells are long lived and are created aft...
Programmed cell death (apoptosis) is sometimes called "controlled cell suicide." Explain what happens during this process and discuss TWO specific consequences that could occur if apoptosis did not occur when it should.Explain how viruses utilize apoptosis in the host cells....
NK cells utilize innate receptors for activation. This allows CAR-NK cells to retain cytotoxic function even if the target molecule changes, potentially overcoming a limitation of CAR-T cell therapy [26]. Additionally, NK cells have a
Here, we show the Fc domain of IgG alone mediates recognition and clearance of herpes simplex virus (HSV1)-infected cells. The human natural killer (NK) cell surface is naturally coated with IgG bound by its Fc domain to the Fcγ receptor CD16a. NK cells utilize the Fc domain of bound...
Given that all of these phosphatases are expressed in NK cells42, we suggest that NK cells may utilize miR-181a to modulate sig- nal strength downstream of receptor engagement to its ligand on cancer cells in breast cancer patients. Sprouty homolog 2 (Spry2), a member of the Sprouty ...

Non-Hodgkin lymphomas (NHL) are cancers of mature B-, T-, and NK-cells which display marked biological heterogeneity between different subtypes. Mature T- and NK-cell neoplasms are an often-aggressive subgroup of NHL and make up approximately 15% of all NHL. Long-term follow up studies have...
Because tumor cells and pathogens can utilize Siglec-7 to escape the immune system, blocking of Siglec-7 binding might be a possible tool for cancer treatment. Therefore, high-affinity Siglec-7 ligands have been designed that are able to overcome the Siglec-7-dependent inhibition of NK cells ...
