People who have had a mild case of COVID-19 are left with long-term antibody protection against future disease, according to a new study.
Metabolic hormone ‘leptin’ linked to poor vaccine response
Reduced levels of a metabolic hormone known as leptin is linked to poor vaccine antibody responses in the general population, a study has found.
Superficial relationship: Enzymes protect the skin by ignoring microbes and viruses
The human body is constantly exposed to various environmental actors, from viruses to bacteria to fungi, but most of these microbial organisms provoke little or no response from our skin, which is charged with monitoring and protecting from external da…
A novel defense mechanism for SARS-CoV-2 discovered
Scientists have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients.
Will COVID-19 eventually become just a seasonal nuisance?
Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lesson…
Antioxidant protein inside the cell worsens inflammation outside
A protein that provides essential protection against free radicals inside the cell provokes damaging inflammation when released outside, activating immune cells and worsening damage following a stroke, according to a new study.
Do COVID-19 vaccines care whether you’re female or male?
A researcher is studying and raising awareness about the role of sex in the efficacy of vaccines that make use of nanomedicine.
Molecule enlists patient’s immune system to combat HIV
Antiretroviral therapy, the common approach in the treatment of HIV, halts replication of the virus and has saved the lives of millions of people. However, for patients the drug cocktail becomes a lifetime necessity because they continue to harbor late…
Novel immunotherapy boosts long-term stroke recovery in mice
Specialized immune cells that accumulate in the brain in the days and weeks after a stroke promote neural functions in mice, pointing to a potential immunotherapy that may boost recovery after the acute injury is over, neurologists found.
Rogue antibodies wreak havoc in severe COVID-19 cases
The development of antibodies to the COVID-19 virus has been the great long-term hope of ending the pandemic. However, immune system turncoats are also major culprits in severe cases of COVID-19, scientists report.
