 Which statement is not true for NKT Cells?

#Unit 4. Cell Communication and Cell Signaling
  1. NKT cells, have received a great deal of recent attention and share features with both conventional T lymphocytes and NK cells.
  2. Like T cells, NKT cells have T-cell receptors (TCRs), and some express CD4. Unlike most T cells, however, the TCRs of NKT cells are not very diverse and recognize specific lipids and glycolipids presented by a molecule related to MHC proteins known as CD1.
  3. Like their innate immune relatives, NK cells, NKT cells have antibody receptors, as well as other receptors classically associated with NK cells. Activated NKT cells can release cytotoxic granules that kill target cells.
  4. they can not also release large quantities of cytokines that can both enhance and suppress the immune response. They appear to be involved in human asthma, but also may inhibit the development of autoimmunity and cancer
