The microbiota is essential to the functioning of the immune system. The nasal milieu secretes immune molecules that can be influenced by diverse bacteria. Hence commensals that enhance anti-viral responses may confer resistance to respiratory viral infection.
Our collaborators have identified 7 microbial state types (CST) defined by indicator species in the nose and recently, through analyses of nasal immune molecules, we have categorized the nasal immune profile types into 8 groups (IPT). Although the IPTs correlated with certain CSTs, the influence of the nasal microbiome on susceptibility to respiratory pathogens is still unknown.
Defining this complex relationship requires a …

Regulation Of Mhc Ii Trafficking And Expression By Host And Viral Factors, Alex Lac
Electronic Thesis and Dissertation Repository
Antigen presentation by major histocompatibility complex class II (MHC II) to the adaptive immune system is crucial for mounting sterilizing immune responses. This central role has made antigen presentation a target for antagonism by many pathogens. Notably, infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) decrease MHC II expression in several immune cells. The mechanisms responsible for this suppression are unknown but involves either redirecting MHC II molecules away from the cell surface or inhibiting MHC II expression. To understand how pathogens manipulate intracellular MHC II trafficking, we first investigated the role of the Golgi trafficking regulator, ERC1, in …

The ongoing Coronavirus Disease 2019 (COVID-19) pandemic is caused by the respiratory virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Similar to other respiratory viruses, SARS-CoV-2 is transmitted through inhalation of respiratory droplets and aerosols from infected individuals. Once inhaled, SARS-CoV-2 utilizes the receptor binding domain (RBD) on the spike protein to bind to human Angiotensin Converting Enzyme 2 (hACE2) receptor to gain entrance into host cells to begin viral replication. SARS-CoV-2 infection can result in mild to severe cases of COVID-19 ranging from asymptomatic infections, cold or flu like symptoms to respiratory failure. The onset of the pandemic in …
