I hypothesize that, as humans are infected with SARS-CoV-2, the virus releases (a) fragment(s) of the spike protein that can target host cells for eliciting cell signaling without the rest of the viral components. Thus, COVID-19 patients are subjected to the intact virus infecting the host cells for the ****tion and amplification as well as the spike protein fragments that are capable of affecting the host cells. I propose that cell signaling elicited by the spike protein fragments that occur in cardiovascular cells wo
