From Olfaction To Immunity: Characterization Of Nasal Immunity In Bony Fish, Ali Sepahi Jul 2018

From Olfaction To Immunity: Characterization Of Nasal Immunity In Bony Fish, Ali Sepahi

Biology ETDs

The olfactory system is a common route pathogen entry in vertebrates. As a consequence, the nasopharynx-associated lymphoid tissue (NALT) needs to rapidly clear infections without compromising the sense of olfaction. NALT is present in teleost fish but its cellular and molecular mechanisms of action have not been investigated to this date. This dissertation focuses on three aims: 1. investigating the role of CCL19-like as a primordial chemokine in vertebrate nasal immunity, 2. determining the presence of tissue microenvironments within the olfactory organ (OO) of rainbow trout, and 3. understanding the immune contributions of olfactory sensory neurons (OSNs) in teleosts against …
