title: Production of two lymphocyte chemotactic factors by antigen-stimulated guinea pig lymphocytes.
abstract: Lymph node cells from guinea pigs sensitized by BCG elaborated two chemotactic factors for lymphocytes when stimulated with purified protein derivative in vitro 4 weeks after immunization. Production of the factors occurred within 24 h of incubation. The two factors were termed alpha- and beta-lymphocyte chemotactic factors (alpha-LCF, beta-LCF), relative to their elution order on gel chromatography. The molecular weights were about 160,000 and 27,000, respectively. alpha-LCF was labile to heating at 56 degrees C for 30 min. Both factors were sensitive to digestion by trypsin, and were effective for T cells but not for B cells.
