CD45, the predominant transmembrane tyrosine phosphatase in leukocytes, is required for the efficient induction of T cell receptor signaling and activation. Various studies have demonstrated that viruses can interfere with the functions of CD45 and that patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are immune-suppressed. We recently reported that the CD45-intracellular signals in peripheral blood mononuclear cells (PBMCs) of triple negative breast cancer (TNBC) patients are inhibited. We also reported that C24D, an immune modulating therapeutic peptide, binds to CD45 on immune-suppressed cells and resets the functionality of the immune system via the CD45 signaling pathway. Given the similarity between the role of CD45 in viral immune suppression, reported by others, and our findings on TNBC, we hypothesized that the C24D peptide may have a similar “immune-resetting” effect. We tested this hypothesis by comparing the CD45 intracellular signaling in PBMC ....

Taï Forest ebolavirus, Reston ebolavirus, Bundibugyo ebolavirus (BDBV), and Bombali ebolavirus. Filoviruses are pleomorphic in shape and possess a lipid envelope. The viral genome is a negative-sense single strand RNA which is approximately 19 kb in size. Since the first outbreak in 1976, EBOV has resurfaced a multitude of times in Africa. Initially, it was responsible for causing small, localized outbreaks until 2013, when the large multinational epidemic was recorded causing 28,646 infections and 11,323 fatalities. 2 A second, large outbreak occurred in the North Kivu province of the Democratic Republic of Congo (DRC) in 2018–2020 totaling 3481 cases and 2299 fatalities. 3,4 There has recently been an outbreak in the Equateur province, which was declared over on November 18th, 2020. ....
