Bacteria inflaming the meninges have developed an immunosuppressive mechanism that contributes to their ability to attack the brain. Researchers found that, by activating pain receptors (nociceptors) to release chemical substances that block an immune cell receptor, Streptococcus pneumoniae and Streptococcus agalactiae deactivated the protective function of macrophages and weakened brain defenses. This, in turn, enabled them to invade the brain.
In a striking demonstration of how the success of mRNA vaccines against COVID-19 has opened up the potential of the technology in cancer, mice that cleared a tumor after a single administration of an mRNA vaccine, also cleared a second tumor without receiving further immunization. This display of potent immunogenicity formed part of a head-to-head study of three different mRNA technology platforms in human papillomavirus (HPV)-16 associated tumors.
TGF-β receptor type-1 (TGFBR1; ALK5; SKR4; TβR-I) inhibitors are reported in a recent Bisichem Co. Ltd. patent as potentially useful for the treatment of cancer, obesity, diabetes, fibrosis, autoimmune diseases and vascular disorders.
Genentech Inc. researchers have described phenol derivatives acting as probable global transcription activator SNF2L2 (SMARCA2; BAF190B; SNF2-α) and/or transcription activator BRG1 (SMARCA4; BAF190A; SNF2-β) degradation inducers reported to be useful for the treatment of cancer.
