[1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
They are key to an experimental autologous cell therapy (Contego) for metastatic melanoma. [15] Autologous TIL therapy for metastatic melanoma has broad T cell recognition of both defined and undefined tumor antigens against all human leukocyte antigen (HLA) restrictions.

Common green frog on top of lilypads and other bog plants. The common green frog (Hylarana erythraea) is a frog species of in the true frog family Ranidae; [2] some sources still use the old name Rana erythraea.
In thin section, quartz grain provenance in a sedimentary rock can be estimated. In crossed polarized light, the quartz grain can go extinct all at once, called monocrystalline quartz, or in waves, called polycrystalline quartz.
