Modulation of Valpha19 NKT cell immune responses by alpha-mannosyl ceramide derivatives consisting of a series of modified sphingosines.

abstract：:Human adherent monocytes were incubated with interferon (IFN) preparations, then washed and stimulated with endotoxins. The interleukin (IL1) activity in the supernatants of IFN-treated monocyte cultures was found to be increased as compared to control (not pretreated) cultures. This phenomenon was observed whether al...
