This article proposes a pathogenesis model for COVID arm along with candidate treatments.

We seek to rapidly identify, test and develop combinations of repurposed drugs to enable cost-effective treatments that reduce the risk of disease or death from SARS-CoV-2 infection. We hypothesize that the morbidity and mortality of COVID-19 reflects overactive host inflammatory responses to infection and is not principally due to the primary dire...

SARS-CoV-2 infection is required for COVID-19, but many signs and symptoms of COVID-19 differ from common acute viral diseases. SARS-CoV-2 infection is necessary but not sufficient for development of clinical COVID-19 disease. Currently, there are no approved pre- or post-exposure prophylactic COVID-19 medical countermeasures. Clinical data suggest...

Abstract BACKGROUND: Up to 80% of SARS-CoV-2 positive patients are asymptomatic and do not appear to progress to COVID-19. SARS-CoV-2 infection is not sufficient for development of COVID-19 disease; this may reflect differences in host inflammatory responses to infection. COX-2 expression is transcriptionally upregulated by SARS nucleocapsid N prot...

Transfection of wounds with DNA-encoding growth factors has the potential to improve healing, but current means of nonviral gene delivery are inefficient. Repeated high doses of DNA, necessary to achieve reliable gene expression, are detrimental to healing. We assessed the ability of in vivo electroporation to enhance gene expression. Full-thicknes...

Nuclease activity present within respiratory tissues contributes to the rapid clearance of injected DNA and therefore may reduce the transfection activity of directly injected transgenes. Most gene transfer technologies transduce or transfect murine tissues more efficiently than corresponding primate tissues. Therefore, it is prudent to assess the...

Naked DNA injection with electropermeabilization (EP) is a promising method for nucleic acid vaccination (NAV) and in vivo gene therapy. Skin is an ideal target for NAV due to ease of administration and the accessibility of large numbers of antigen-presenting cells within the tissue. This study demonstrates that in vivo skin EP may be used to incre...

Two mammary tumors developed in feral mice treated with dimethylbenzanthracene. The tumors, livers, and spleens of these animals contained no MuMTV proviral DNA. Neither tumor had amplified or rearranged int-1 or int-2 loci. This demonstrates that mammary tumorigenesis can occur in mice in the absence of endogenous and exogenous MuMTV.

Laboratory colonies of feral mice (Mus musculus domesticus) have been established with specific mouse mammary tumor virus (MuMTV) genotype, including colonies lacking any proviral DNA (ev-) or carrying only a single copy of MuMTV DNA (ev+). No evidence of a decline in reproductive capacity has been observed in the first 8 generations. Both the ev-...
