Abstract

BACKGROUND: Microbial exposure might play a key role in allergy development, but little is known about the role of Toll-like receptors (TLRs).OBJECTIVE: This study explored the association between neonatal TLR microbial recognition/function, allergy risk (maternal allergy), and prospective allergy d...
