Dectin-1 Mediated Mechanical Force Generation In Candida Albicans Fungal Pathogen Recognition, Rohan Choraghe
Dectin-1 Mediated Mechanical Force Generation In Candida Albicans Fungal Pathogen Recognition, Rohan Choraghe

Candida spp. pathogens continue to be a major health care burden with high mortality and exceeding a billion dollars in terms of healthcare cost. Candidainfection ranges from superficial dermatological infection to more serious blood stream infection in debilitated patients. One of the major lines of innate immune defense against Candidais phagocytosis. Dectin-1 is the antifungal receptor in myeloid cells responsible for most immune responses against fungi including phagocytosis. We looked into the signaling pathway coordinating this mechanical process downstream of Dectin-1. We found that Dectin-1 activation gives rise to a significant mechanical force generation mediated through RHOA-ROCK-MyosinII pathway. …

The cell surface is the first interface the host immune system encounters and
its investigation has led to a better understanding of cellular biology and types of
pathways that pathogens target in a host cell. The cell surface has evolved to include
many functions such as manipulation of the cytoskeleton, cell signaling, membrane
trafficking, adhesion, and integration into host tissue. The pathogens of interest are
the pathogenic fungus, Candida albicans, and the parasite, Giardia lamblia and we
investigate the consequences of drug treatments on the cell surface, leading to
promising new targets.
