phytohemagglutinin การใช้

• CCL17 is expressed constitutively in thymus, but only transiently in phytohemagglutinin-stimulated CCR4.
• Expression is induced by phytohemagglutinin in human lymphocytes and by serum stimulation of arrested fibroblasts.
• At least broad beans also contain the lectin phytohemagglutinin and are somewhat poisonous if eaten raw.
• Similar to phytohemagglutinin ( PHA ), it is a selective T cell mitogen relative to its effects on B cells.
• On the other hand, delayed-type hypersensitivity, and splenic cell mitogen responses to phytohemagglutinin and concanavalin A did not differ among mice fed the various diets.
• In the mid-1970s, it was discovered that T-cells could be selectively proliferated when normal human bone marrow cells were cultured in conditioned medium obtained from phytohemagglutinin-stimulated normal human lymphocytes.
• For example, chrysotile fibres have been shown to depress the in vitro proliferation of phytohemagglutinin-stimulated peripheral blood lymphocytes, suppress natural killer cell lysis and significantly reduce lymphokine-activated killer cell viability and recovery.
• A soluble factor ( s ) generated by antigen or phytohemagglutinin stimulation of leishmania-specific CD4 + helper T cells from skin-test positive adults killed CD8 + T cells but not CD4 + helper T cells when added to culture media.
• The effect of graded amounts of dietary laetalbumin ( L ) and casein ( C ) hydrolyzates on the immune responsiveness of C3H / HeN and DBA / 2 strain mice has been investigated by measuring both the specific humoral immune response to sheep red blood cells ( SRBC ) and the nonspecific splenic cell responsiveness to phytohemagglutinin, concanavalin A and Escherichia coli lipopolysaccharide after stimulation with Mycobacteriurn bovis, strain BCG . The nutritional efficiency of these diets was similar at both 12 and 28 % amino acid levels.
