Gut microbiota-derived metabolites confer protection against SARS-CoV-2 infection [16S rRNA]

Project description:The gut microbiome is intricately coupled with immune regulation and metabolism, but its role in Coronavirus Disease 2019 (COVID-19) is not fully understood. Severe and fatal COVID-19 is characterized by poor anti-viral immunity and hypercoagulation, particularly in males. Via 16S sequencing of antibiotic-treated mice, we found that Clostridia species protect mammalian hosts from SARS-CoV-2 intranasal infection, both locally and systemically, via production of short-chain fatty acids (SCFAs). SCFAs reduced viral burdens in the airways and intestines by downregulating the SARS-CoV-2 entry receptor, angiotensin-converting enzyme 2 (ACE2), and enhancing adaptive immunity in male animals. In order to identify other mechanisms by which SCFAs influence the outcome of SARS-CoV-2 infection, we performed RNA-seq on lungs from male GF mice given control or SCFA water for two weeks. We identified a novel role for the gut microbiome in regulating systemic coagulation response by limiting megakaryocyte proliferation and platelet turnover via the Sh2b3-Mpl axis. Taken together, our findings have unraveled novel functions of SCFAs and fiber-fermenting gut bacteria that might be leveraged as pan-coronavirus therapeutics to dampen viral entry and hypercoagulation and promote adaptive anti-viral immunity.

Severe and fatal COVID-19 is characterized by poor anti-viral immunity and hypercoagulation, particularly in males. Here we define multiple pathways by which the gut microbiome protects mammalian hosts from SARS-CoV-2 intranasal infection, both locally and systemically, via production of short-chain fatty acids (SCFAs).

Mucosal Boosting Enhances Vaccine Protection Against SARS-CoV-2 in Rhesus Macaques

Project description:A major limitation of current SARS-CoV-2 vaccines is that they provide minimal protection against acquisition of infection with current Omicron subvariants, although they still provide protection against severe disease. It has been hypothesized that enhanced mucosal immunity will be required to block infection and onward transmission. Intranasal administration of current vaccines has proven inconsistent, suggesting that alternative immunization strategies may be required. Here we show that intratracheal boosting with a bivalent Ad26 based SARS-CoV-2 vaccine results in substantial induction of mucosal humoral and cellular immunity and near complete protection against SARS-CoV-2 BQ.1.1 challenge.

Inhalation of ACE2-expressing lung spheroid cell exosomes provides prophylactic protection against SARS-CoV-2

Project description:We demonstrated that lung spheroid cell derived exosomes (LSC-Exo) carry the parental cell’s ACE2 that are able to target lung, intercept SARS-CoV-2 entry, confer protection against SARS-CoV-2 infection. This LSC-Exo prophylaxis paradigm would not be limited by viral evolution, showing great potential for emerged SARS-CoV-2 variants, including those that are yet to emerge.
