"Since 2022 weve seen a sharp rise in most types of cancer among working-age adults in England. The data dont yet tell us why - but the trend is clear. If confirmed this could turn out to be one of the most serious public health failures in modern history. @szupraha @ZdravkoOnline @adamvojtech86"

"Yes we wrote about this study. It is important. A study from Cambridge in Brain shows that even months after COVID-19 survivors still carry measurable inflammation-related changes in the brainstem - the part of the brain that keeps you breathing awake and alive🧵"

"SARS-CoV-2 carries proteins designed to manipulate immune signaling inside the brain. Several of them target the same pathways that keep microglia and neurons in balance. Together these proteins dont just infect cells - they reprogram innate immunity inside the nervous system"

"The authors (Salamon Pretorius Ewing Bar-Yam and others) review a large body of evidence. Their conclusion - SARS-CoV-2 is not HIV - but it shares key biological traits with it - immune exhaustion viral persistence and systemic inflammation"

"Unlike HIV SARS-CoV-2 spreads through the air infects repeatedly and leaves a cumulative immune toll on the population. Reinfections are not harmless - they may compound immune and neurological damage over time"

"In a mouse model of EBV-related cancer V1 cells migrated straight into the tumor became activated and slowed tumor growth. Not a cure yet - but a clear biological signal that this immune pathway could be harnessed therapeutically"

"Meanwhile increased RD in the right amygdala may signal microstructural stress - poorer myelin integrity and disrupted emotional processing. So structural change on both sides but in different directions"

"The longer the smell loss lasted the stronger the DTI changes - especially in the amygdala and piriform cortex. That points to ongoing remodeling not a static injury"

"And thats where the parallels emerge: HIV EBV CMV - all use similar tricks to hide persist and exhaust. SARS-CoV-2 seems to have learned the same playbook"

"Its a warning sign that SARS-CoV-2 can disrupt brain balance in a way that closely resembles early neurodegenerative changes. That doesnt mean everyone will develop dementia - but it suggests the brain may enter a similar trajectory of inflammation and stress if these processes arent stabilized"

"@ClubEffective @mdkatrsk Good catch. The data come from the same MGH pediatric cohort previously analyzed by the Walt lab using Simoa. That assay detects full-length viral spike confirming infection-derived antigenemia rather than a vaccine source"

"Biological consequences. This long-term shutdown of the repair program can cause chronic fatigue and poor microcirculation increase the risk of microclots and vascular aging and potentially underlie Long COVID itself"

"These patients were infected with early variants (Wuhan/Alpha) - the ones with a strong affinity for blood vessel cells. But the mechanism - the switching off of KLF2eNOS signaling - could still happen with newer variants just more quietly"

"Why it matters. EBV is linked to certain cancers and autoimmune diseases. V1 T cells could offer a new way to target infected or malignant cells that evade classical immune recognition - and they could be made off the shelf usable for any patient"

"Possibly one of the most important studies on EBV and human immunity in a long time. It shows that a special type of immune cell - T cells (V1) - can detect and destroy EBV-infected cells even when the virus hides from the classical immune system.🧵"

"Thats why women are more likely to experience long COVID symptoms that look autoimmune - persistent inflammation exhausted T cells (PD-1+ CTLA-4+ LAG-3+) and low-grade neuroinflammation without viral persistence. The virus leaves - but the immune activation stays"

"In other words. SARS-CoV-2 doesnt just trigger a transient immune response - it epigenetically reprograms X-linked genes. This may cause long-term immune dysregulation even in previously healthy women"

"@cfs_research I get your frustration. The signal is there just not replicated robustly mostly because of small samples and variability in TSPO binding ligand affinity PET correction methods"

"COVID-19 doesnt just cause inflammation. It switches off the genes that repair blood vessels - and switches on those that drive inflammation and destruction. And whats worse - this state lasts for at least six months long after the infection is gone🧵"
