Immunomodulation by Bacillus subtilis spores. 1983

G Benedettini, and G De Libero, and R Pierotti, and M Campa, and G Falcone

This study was undertaken in order to investigate the immunomodulatory effect of heat-killed Bacillus subtilis spores as well as of one soluble and one insoluble fraction obtained after their mechanical breakage. The results demonstrate that heat-killed spores, the soluble and the insoluble fraction enhance the primary PFC response to T-dependent antigens such as SRBC and HRBC, but not to T-independent antigens such as Ficoll-TNP. However, the same doses capable of enhancing the production of antibodies against T-dependent antigens were unable to modify the host CMI, evaluated in terms of contact sensitivity to oxazolone.

UI	MeSH Term	Description	Entries
D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.
