Preclinical evaluation of antigen-sensitive B7-H3-targeting nanobody-based CAR-T cells in glioblastoma cautions for on-target, off-tumor toxicity.

Background: Glioblastoma is the most common lethal primary brain tumor, urging evaluation of new treatment options. Chimeric antigen receptor (CAR)-T cells targeting B7 homolog 3 (B7-H3) are promising because of the overexpression of B7-H3 on glioblastoma cells but not on healthy brain tissue. Nanobody-based (nano)CARs are gaining increasing attention as promising alternatives to classical single-chain variable fragment-based (scFv)CARs, because of their single-domain nature and low immunogenicity.

BDNF methylation associated with stress in women: Novel insights in epigenetics and inflammation.

The brain-derived neurotrophic factor (BDNF) gene plays an important role in modulating the stress-response axis and inflammation, which can be regulated by epigenetic mechanisms. BNDF methylation has been associated with stress-related psychiatric disorders such as depression, anxiety and post-traumatic stress. Previous studies have reported that stressful events are involved with long-lasting alterations in DNA methylation (DNAm) of the BNDF exon IV promoter, suggesting that glucocorticoids and inflammatory cytokines can regulate this process.
