Ceramide glucosyltransferase (CGT) adds sugar moieties to ceramide, forming glucosylceramides that play roles in immune signaling, stress response, and host-bacterial interactions. Here, we examined whether mutations in cgt block the beneficial effects of Bacillus subtilis on C. elegans lifespan. We found that loss of cgt-1 or cgt-3 reduces lifespan compared to wildtype worms, but did not prevent the lifespan-extending phenotype of B. subtilis. However, cgt-1(ok1045) and cgt-3(tm504) did play a minor role in blocking stress resistance of 5-day old worms treated with B. subtilis. Further studying CGTs may elucidate potential roles of glucosylceramides in host-bacterial interaction.
