Type III interferons: Protective or harmful in COVID-19?
Interferons and other cytokines produced by the immune system are important defenses against viral infections, but as we have seen in COVID-19, they can also contribute to damaging, potentially life-threatening lung inflammation. Recent evidence suggests that one type of interferon, known as type III interferon or interferon lambda (λ), can fight viral infection while limiting this inflammatory damage. That has led to clinical trials to test type III interferon as a treatment for COVID-19. (2020-06-11)

(2020-02-26)

McMaster researchers uncover hidden antibiotic potential of cannabis
The research team found that CBG had antibacterial activity against drug-resistant MRSA. It prevented the ability of that bacteria to form biofilms, which are communities of microorganisms that attach to each other and to surfaces; and it destroyed preformed biofilms and cells resistant to antibiotics. CBG achieved this by targeting the cell membrane of the bacteria. These findings in the laboratory were supported when mice with an MRSA infection were given CBG. (2020-02-26)

No benefit found in using broad-spectrum antibiotics as initial pneumonia treatment
