Researchers have developed a new brain organoid model to study the mechanistic causes of Alzheimer's disease and test dementia drugs currently in development.
ApoE4, a gene associated with an increased risk of Alzheimer's disease, also appears to increase susceptibility and the severity of COVID-19. SARS-CoV-2, the virus responsible for coronavirus, increased susceptibility to COVID-19 in ApoE4 neurons and astrocytes in brain organoid models.
Capsular polysaccharide A (PSA), an envelope molecule, may help to boost the immune system and protect against potentially fatal neuroinflammation associated with Herpes Simplex Encephalitis (HSE). Mice given PSA survived exposure to a lethal herpes simplex viral infection, while those not treated with the probiotic did not, despite both groups being treated with a common antiviral used to treat HSE.
