Immunity from non-immune cells

IP: Joan Manils Pacheco, PhD

The human body reacts to dangers such pathogenic microorganisms or tissue damage with a physiological response called inflammation. While inflammation is critical for regeneration and homeostasis, it is also a common driver of pathologies such as autoimmunity and cancer when malfunctioning. Virtually each one of the cells composing the body can kickstart inflammation, and this is largely due to the presence of the transcription factor NF-KB in all of them.

Keratinocytes are active players of the innate immune system; they express a wide variety of receptors to sense pathogens and damage and release proinflammatory cytokines in response to insults. Keratinocytes have their own and unique way to activate NF-KB through CARD14 protein. CARD14 acts as an assembly point for adaptors creating a node that promotes signals within the cell leading to inflammation and skin diseases such psoriasis when mutated. We aim to gain insights into CARD14 fundamental biology, using animal models and molecular approaches to understand and manipulate its activity to fight psoriasis.
