Abstract: Nutrition and infection have been studied for over a century, yet even now there is much still to be learned. What is becoming clear is that micronutrients, such as vitamin A, play multiple roles both in protective mucosal immunity and barrier functions, and in the acute response to infection. Recent research has revealed novel mechanisms, several involving mucosal immunity and host-microbiome interactions. This lecture, focusing on examples from vitamin A research, will bring to the fore several of the fascinating ways that micronutrients contribute to host defense against infectious diseases.
