Effect of triacontanol on numbers and functions of cells involved in inflammatory responses

Proc Soc Exp Biol Med. 1992 Jul;200(3):349-52. doi: 10.3181/00379727-200-43441.


A preparation of a triacontanol-containing compound was studied for its effect on cells involved in the inflammatory response. C57BL/6 mice were injected intraperitoneally with various concentrations of this compound and investigated for total body weight, wet weight of thymus tissue, number of thymus cells and splenocytes, interleukin 1 production of spleen monocytes, and response of splenocytes to the T cell mitogen, phytohemagglutinin. Mice treated with the triacontanol preparation exhibited decreased total body weight, 24% reduction in thymus weights, 39% decrease in the number of thymus cells, and 21% depression in total splenocytes. Splenic monocytes of these animals produced a significantly reduced amount of interleukin 1 and splenocytes had a significantly depressed response to phytohemagglutinin. It is concluded that triacontanol has an inhibitory effect on at least some of the cells responsible for inflammation.
