Background: Clostridium butyricum is a probiotic widely used in animal husbandry, and there is evidence to suggest that it can alleviate intestinal inflammation in pigs and may be related to its lipoteichoic acid (LTA), but the mechanism is still unclear.
Objective: This study aimed to determine the regulatory effect and potential mechanism of C. butyricum LTA on LPS-stimulated inflammation in intestinal porcine epithelial line-J2 (IPEC-J2).

Electronic address:
Staphylococcus aureus is a major human pathogen, yet the immune factors that protect against infection remain elusive. High titers of opsonic IgG antibodies, achieved in preclinical animal immunization studies, have consistently failed to provide protection in humans. Here, we investigate antibody responses to the conserved S.

Unlabelled: Some strains of lactic acid bacteria can regulate the host's intestinal immune system. Bacterial cells and membrane vesicles (MVs) of JCM 15950 promote immunoglobulin A (IgA) production in murine Peyer's patch cells via toll-like receptor (TLR) 2. This study aimed to investigate the role of lipoteichoic acid (LTA), a ligand of TLR2, in the immunostimulatory activity of these bacterial cells and their MVs.
