Relevance of SARS-CoV-2 related factors ACE2 and TMPRSS2 expressions in gastrointestinal tissue with pathogenesis of digestive symptoms, diabetes-associated mortality, and disease recurrence in COVID-19 patients

TLDR
It is hypothesize that SARS-CoV-2 host cell entry receptor—ACE2 based mechanism in GI tissue may be involved in COVID-19 in the pathogenesis of digestive symptoms, in increased diabetic complications, and in disease recurrence.

COVID-19 Mechanisms in the Human Body-What We Know So Far.

TL;DR: A review of the progress made since the commencement of the COVID-19 pandemic can be found in this article, where the authors narrate the progress in the human body, including virus-host interactions, pulmonary and other systemic manifestations, immunological dysregulations, complications, host-specific vulnerability, and long-term health consequences in the survivors.

Neurological Symptoms of COVID-19: The Zonulin Hypothesis.

TL;DR: In this paper, the authors proposed an alternative pathway from the infection of the gut, involving Toll-like receptor 4 (TLR4), zonulin, protease-activated receptor 2 (PAR2), and Zonulin brain receptor.

Structure, Function, and Antigenicity of the SARS-CoV-2 Spike Glycoprotein.

TL;DR: It is demonstrating that cross-neutralizing antibodies targeting conserved S epitopes can be elicited upon vaccination, and it is shown that SARS-CoV-2 S uses ACE2 to enter cells and that the receptor-binding domains of Sars- coV- 2 S and SARS S bind with similar affinities to human ACE2, correlating with the efficient spread of SATS among humans.

Tissue distribution of ACE2 protein, the functional receptor for SARS coronavirus. A first step in understanding SARS pathogenesis

TL;DR: ACE2 is abundantly present in humans in the epithelia of the lung and small intestine, which might provide possible routes of entry for the SARS‐CoV.

Structural basis for the recognition of SARS-CoV-2 by full-length human ACE2.

TL;DR: Cryo–electron microscopy structures of full-length human ACE2 in the presence of the neutral amino acid transporter B0AT1 with or without the receptor binding domain (RBD) of the surface spike glycoprotein of SARS-CoV-2 are presented, providing important insights into the molecular basis for coronavirus recognition and infection.
