The COVID-19 pandemic caused by SARS-CoV-2 infection has led to socio-economic shutdowns and the loss of over 5 million lives worldwide. There is a need for the identification of therapeutic targets to treat COVID-19. SARS-CoV-2 spike is a target of interest for the development of therapeutic targets. We developed a robust SARS-CoV-2 S spike expression and purification protocol from insect cells and studied four recombinant SARS-CoV-2 spike protein constructs based on the original SARS-CoV-2 sequence using a baculovirus expression system: a spike protein receptor-binding domain that includes the SD1 domain (RBD) coupled to a fluorescent tag (S-RBD-eGFP), spike ectodomain coupled …

Multiple organ damage is common in patients with severe COVID-19, even though the underlying pathogenic mechanisms remain unclear. Acute viral infection typically activates type I IFN (IFN-I) signaling. The antiviral role of IFN-I is well characterized in vitro. However, our understanding of how IFN-I regulates host immune response to SARS-CoV-2 infection in vivo is incomplete. Using a human ACE2-transgenic mouse model, we show in the present study that IFN-I receptor signaling is essential for protection against the acute lethality of SARS-CoV-2 in mice. Interestingly, although IFN-I signaling limits viral replication in the lung, the primary infection site, it is dispensable …

During the COVID-19 pandemic, HIV clinics had to transform care delivery for people with HIV (PWH). We developed a multifaceted telehealth implementation strategy and monitored number of out of care patients (OOC), medical visit frequency (MVF), gap in care (GiC) and viral suppression (VS), and compared measures to baseline data. Between April and October 2020, 1559 visits were scheduled; 328 (21%) were missed, and 63 (4%) were new to care. Of the remaining 1168 follow-up visits, 412 (35%) were telehealth visits. As of October 2020, there were 53 patients OOC, MVF was 55% and GiC was 24% compared to 34, …

The SARS-CoV-2 virus outbreak has underscored numerous weak links in our biodefense countermeasures against highly communicable diseases. Many believe it was our lack of an effective testing model that allowed the virus to become a global pandemic within a short period. The gold standard collection method for the SARS-CoV-2 virus involves mechanical debridement of the nasopharyngeal cavity with a stiff swab applicator, which has been known to cause pain and injury to patients, subsequently resulting in low patient acceptance of the procedure. Due to the invasive nature of the nasopharyngeal swab collection method, it may not be conducive to the …

The severe acute respiratory syndrome SARS-CoV-2 pandemic has posed significant challenges to hospital and public health systems in the United States. In response to a shortage in nasopharyngeal swabs, our institution developed, tested, and deployed 3D-printed swabs to obtain a specimen for testing. A patient was tested in preparation for a scheduled Esophagogastrodeuodenoscopy. During the procedure the swab broke and a portion remained in the superior meatus and olfactory cleft. This case study describes the process of locating and removing the broken sections of the 3D-printed swab. In response to this incident, 3D-printing teams test swabs for sample collection and …
