Does smoking increase risk of COVID-19 hospitalization?

A study conducted by UK researchers has found that patients hospitalized with coronavirus disease 2019 (COVID-19) were less likely to be current smokers than patients who had been admitted with other types of respiratory viral infections last year (2019).

Researchers discover molecular mechanism of long-term memory

Researchers at the University of Basel have discovered a molecular mechanism that plays a central role in intact long-term memory. This mechanism is also involved in physiological memory loss in old age.

Ipom-F inhibits SARS-CoV-2 infection in vitro

An international team of researchers showed the small molecule inhibitor, ipomoeassin F (Ipom-F), blocks the translocation/insertion of the three protein targets for SARS-CoV-2 infection.

SARS-CoV-2 spike protein antibodies can persist up to 200 days after symptom onset

Researchers report SARS-CoV-2 antibodies to the spike protein (S protein) can persist 200 days after symptom onset, but that antibodies to the nucleoprotein (N protein) can reduce much more rapidly.

Is COVID-19 severity mediated by higher antibody response?

A new study indicates that patients with more severe COVID-19 have a stronger antibody response.

Mefloquine shows potential as anti-SARS-CoV-2 drug

A team of scientists from Japan has identified the approved anti-material drug, mefloquine, as a potential candidate to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Specifically, mefloquine has been shown to prevent the entry of SARS-CoV-2 into host cells and reduce the viral load in vitro.

SARS-CoV-2 suppresses ACE2 activity in COVID-19 patients

A recent study conducted by a team of international scientists has revealed that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), suppresses the expression and function of human angiotensin-converting enzyme 2 (ACE2) and induces the expression of interferon-stimulated genes at the initial phase of infection. The study is currently available on the bioRxiv* preprint server.
