SARS-CoV-2-specific virulence factors in COVID-19.
Ashutosh Kumar,Pranav Prasoon,Chiman Kumari,Vikas Pareek,Muneeb A. Faiq,Ravi K. Narayan,Maheswari Kulandhasamy,Kamla Kant +7 more
TL;DR: Investigators provided robust evidence that SARS‐CoV‐2‐specific virulence factors may have an impact on viral infectivity and transmissibility and disease severity as well as the development of immunity against the infection, including response to the vaccines.
Journal ArticleDOI
Sars-Cov-2 Cell Entry Receptor Ace2 Mediated Endothelial Dysfunction Leads to Vascular Thrombosis in COVID-19 Patients
Ashutosh Kumar,Ravi K. Narayan,Chiman Kumari,Muneeb A. Faiq,Maheswari Kulandhasamy,Kamla Kant,Vikas Pareek +6 more
TL;DR: This work proposes a SARS-CoV-2 cell entry receptor ACE2 based mechanism for vascular thrombosis in COVID-19 patients, which is based on the circumstantial evidence present in the literature.
Journal ArticleDOI
Possible routes of SARS-CoV-2 invasion in brain: In context of neurological symptoms in COVID-19 patients.
Ashutosh Kumar,Vikas Pareek,Pranav Prasoon,Muneeb A. Faiq,Pavan Kumar,Chiman Kumari,Ravi K. Narayan +6 more
TL;DR: This review article has discussed the possible routes of SARS‐CoV‐2 brain entry based on the emerging evidence for this virus, and that available for other betacoronaviruses in literature.
Journal ArticleDOI
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
Ashutosh Kumar,Muneeb A. Faiq,Vikas Pareek,Khursheed Raza,Ravi K. Narayan,Pranav Prasoon,Pavan Kumar,Maheswari Kulandhasamy,Chiman Kumari,Kamla Kant,Himanshu Narayan Singh,Rizwana Qadri,Sada N. Pandey,Santosh Kumar +13 more
TL;DR: 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.
Journal ArticleDOI
COVID-19 Mechanisms in the Human Body-What We Know So Far.
Ashutosh Kumar,Ravi K. Narayan,Pranav Prasoon,Chiman Kumari,Gurjot Kaur,Santosh Kumar,Maheswari Kulandhasamy,Kishore Sesham,Vikas Pareek,Muneeb A. Faiq,Sada N. Pandey,Himanshu Narayan Singh,Kamla Kant,Prakash Singh Shekhawat,Khursheed Raza,Sujeet Kumar +15 more
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.
