β‐glucan recognition by the innate immune system
TL;DR: This review explores what is currently known about β‐glucan recognition and how this recognition stimulates immune responses, and special emphasis is placed on Dectin‐1, as the authors know the most about how this key β‐ glucan receptor translates recognition into intracellular signaling, stimulates cellular responses,and participates in orchestrating the adaptive immune response.
