Raynaud Syndrome: What Cold Fingers Really Signal—and How to Manage It

Raynaud phenomenon occurs when small blood vessels overreact to cold or stress, causing color changes in fingers/toes (blue, white, red) and sometimes ulcers; primary Raynaud is common and usually harmless, while secondary Raynaud can accompany autoimmune diseases and be more severe. Diagnosis uses nailfold capillaroscopy and blood tests; treatments include off-label options like calcium channel blockers and, in severe cases, epoprostenol infusions. Prevention focuses on avoiding triggers, gradual warming, staying warm, stress reduction, and minimizing caffeine, nicotine, and other vasoconstrictors.

Commensal gut bacteria wield secretion systems to tune human immunity

A large analysis of healthy human gut bacteria shows that about 80% of Pseudomonadota carry intact type III secretion systems, with over 90% possessing a host-directed secretion system. The researchers built a meta-interactome linking commensal effectors to human proteins, finding effector-target neighborhoods enriched for genetic variation tied to immune and metabolic diseases. Metagenomic data show effector enrichment in Crohn’s disease but depletion in ulcerative colitis. Functionally, commensal effectors can translocate into human cells and modulate NF-κB signaling and cytokine secretion in vitro, suggesting T3SS contribute to microbiome–host communication and may influence health and disease.

Alzheimer’s Reimagined as an Immune-System Brain Disorder

The piece argues Alzheimer's may be primarily an autoimmune disorder of the brain rather than just a brain disease, challenging the traditional beta-amyloid focus and the controversial aducanumab approval. It posits beta-amyloid may be part of the brain’s immune response that goes awry, driving dementia, while other theories (mitochondrial dysfunction, infections, metal handling) gain traction. With Alzheimer's affecting tens of millions worldwide, the article calls for new immune- and mechanism-based therapies and directions.

UK's First MS Patient Trials Groundbreaking 'Gamechanger' Treatment

A Hertfordshire mother and biology teacher, Emily Henders, has become the first UK patient to receive a pioneering CAR T cell therapy in a clinical trial aimed at treating multiple sclerosis, a disease that causes immune system attacks on nerves. The experimental treatment, which depletes B cells to reset the immune system, offers hope for slowing or halting disease progression and could be a gamechanger if successful.

Monica Seles Opens Up About Her Myasthenia Gravis Battle and Reset

Tennis legend Monica Seles has revealed her diagnosis of myasthenia gravis, a rare autoimmune neuromuscular disease, to raise awareness. The disease causes muscle weakness and fatigue, affecting her daily life, and has no cure but can be managed with treatment. Seles shared her experience ahead of the U.S. Open to educate others about the condition.
