Abstract:
:Toll-like receptor 7 is critical in recognition of single strand RNA viruses, including SARS CoV-2, and generation of anti-viral immunity. Coronaviruses evolved strategies to dampen the host immunity. Herein, we discuss the potential use of TLR7 agonists in the early stages of COVID-19 treatment.

信件abstract::Chronic, tertiary Lyme disease, a vector-borne infection most accurately designated neuroborreliosis, is often misdiagnosed. Infectors of the human brain, Lyme borrelial spirochetes are neurotropic, similar to the spirochetes of syphilis. Symptoms of either disease may be stable and persistent, transient and inconsist...
