Gram‐positive bacteria on grass pollen exhibit adjuvant activity inducing inflammatory T cell responses

Abstract

These data indicate that grass pollen is colonized by several microorganisms that influence the immune response differently. Similar to LPS, supernatants of homogenized Gram-positive bacteria may serve as adjuvants by augmenting DC maturation and inflammatory Th1, Th2 and Th17 responses helping to initiate allergic immune responses.
