- A new searchable LibGen torrent index (https://zrthstr.github.io/libgen_torrent_cardiography/index.html) was shared that lets users sort mirrors by seed count, providing a resilient way to access scientific literature.  
- Discussion of immune-tolerance mechanisms centered on whether targeted “off switches” for misbehaving antibody production could be engineered by repopulating bone marrow with tolerogenic antigen-presenting cells.  
- Links to tolerogenic dendritic cells (https://en.wikipedia.org/wiki/Tolerogenic_dendritic_cell) and Treg epitopes (https://pmc.ncbi.nlm.nih.gov/articles/PMC3714563/) were provided as evidence that regulatory T-cell modulation can induce antigen-specific tolerance in mice, with speculation on translating this to human autoimmune therapy.  
- Anecdotal report from the Shroomery forum (https://www.shroomery.org/forums/showflat.php/Number/19247881) claimed that LSD use diminished cat allergies, prompting debate on whether psychedelics could modulate immune hypersensitivity.  
- Participants explored why fetomaternal microchimerism does not trigger maternal immune rejection; explanations included PD-L1 expression on placental cells, anti-inflammatory cytokines (IL-10, TGF-β), hormonal suppression via hCG and progesterone, and the possibility that yolk-sac–derived fetal cells are inherently less immunogenic.
