title: Immunopotentiation by pyrimethamine in the mouse.
abstract: Pyrimethamine, a 2,4-diaminopyrimidine useful in the treatment of malaria and toxoplasmosis, was found to enhance antibody and delayed-type hypersensitivity responses to sheep red cells in mice. The immunodepression of tumour-bearing mice was also reversed by pyrimethamine. This drug may prove useful as a general immunostimulant in clinical situations where the immune system has been compromised by cancer or other debilitating illnesses.
