tests of cerebral lateralization. 1  sodium amytal test: anesthetize one hemisphere and check for language function. 2  dichotic listening test: report more digits heard by dominant half. 3  functional brain imaging: fMRI or PET used to see which half is active when performing a language test.
one of a large group of low-molecular-weight proteins secreted by various cell types and involved in cell-to-cell communication, coordinating antibody and T cell immune interactions, and amplifying immune reactivity. Cytokines include colony-stimulating factors, interferons, interleukins, and lymphokines, which are secreted by lymphocytes.
Following the innate immune response, which includes phagocytosis and the release of cytokines, the expression of MHC Class II molecules on macrophages are up regulated to function as antigen presenting cells to promote the antigen- specific or adaptive immune response. 2. Natural Killer Cells
