A study with data from ~14 million children shows that COVID19 infection is significantly more harmful to kids’ hearts than the vaccine.
Marty Makary falsely alleged that “children died” because from COVID19 vaccine. Whomever told him that failed to account for SARS-CoV-2 infections.

Immunology as a guide to human relationships #immunology
Immunology as a guide to human relationships
This essay uses immunology to illuminate human relationships. Moving beyond self/non-self toward danger-based models, it draws parallels between cytokine communication and language, tolerance and forgiveness, microbiota diversity and coexistence. Recognizing these metaphors reveals pathways toward healthier connections within individuals, communities, and societies.

Keep your neutrophils close, but your mast cells closer
Immune activity at the cerebrospinal fluid (CSF)–dura–brain interface regulates key functions of brain physiology. In two back-to-back papers, Mamuladze et al. and Kothari et al. show that dural mast cells (MCs) are strategically positioned to coordinate this regulation, controlling CSF flow dynamics and immune cell trafficking in allergy, meningitis, and stroke.

Another great paper adding to our understanding of macrophage-neuron interactions shaping myeloid and nerve identity (here via TGFb signalling). Led by @philipp359.bsky.social from Freiburg. Out now open access in @cp-immunity.bsky.social:
Sensory neurons shape local macrophage identity via TGF-β signaling
Specialized macrophages are known to persist within tissue niches, but the molecular
mechanisms guiding their sustained functional adaptation remain unclear. Kolter and
Döring et al. show that local interactions between sensory nerves and macrophages
activate TGF-β, which imprints and maintains nerve-associated macrophages that contribute
to regeneration after tissue injury.
