Lymphocyte-induced angiogenesis (LIA), a vascular response was observed when allogenic immunocompetent lymphocytes of C3H/w mice infected with Trichinella spiralis were inoculated intradermally into irradiated BALB/c. It was shown that intestinal phase of T. spiralis infection stimulated mainly CD5 T cells dependent angiogenesis. The enhancement of angiogenesis did not occur in the early and late muscular phases of the infection. It is suggested, that changes in the intensity of angiogenesis may play a role in spreading of new-born larvae in the host.
