Richard L. Gallo is an American dermatologist who is a Distinguished Professor and founding Chairman of Dermatology at the University of California, San Diego.
[4] Subsequent work from his laboratory used molecular techniques to produce a knock out mouse that has shown how cathelicidin antimicrobials protect against infection in several organs including the skin.
[5] By using a wide variety of biochemical and genetic tools his work has also shown that other antimicrobial peptides and elements of innate immunity such as Toll-like receptors and Hyaluronan influence human health.
Most recently his research has defined biochemical mechanisms through which Vitamin D and the normal skin microflora Microbiome can control immune responses.
These latest findings have advanced understanding of the Hygiene hypothesis, Atopic Dermatitis and Rosacea.
