Immune therapies are shifting from broad suppression to precise re-calibration—targeting specific cells, pathways, and restoring balance for better outcomes with fewer side effects.| David Lingenfelter, PhD
SARS-CoV-2 accelerates immune aging, shrinking T-cell diversity and telomeres, raising risks for Long COVID, infections, and cancer.| David Lingenfelter, PhD
Severe COVID-19 causes lasting damage to lymphoid organs, impairing immune memory, increasing infection risk, and accelerating immune aging.| David Lingenfelter, PhD
SARS-CoV-2 may trigger autoimmune diseases, especially Sjögren’s-like syndrome, but links to RA and SLE remain unclear due to conflicting data and genetic variability.| David Lingenfelter, PhD
SARS-CoV-2 reprograms innate immunity via epigenetic changes, causing chronic inflammation and Long COVID symptoms by altering stem cells and immune responses.| David Lingenfelter, PhD
SARS-CoV-2 triggers diverse autoantibodies via molecular mimicry and immune dysregulation, contributing to Long COVID symptoms like fatigue, brain fog, and organ dysfunction.| David Lingenfelter, PhD
COVID-19 can cause temporary testicular damage via inflammation, autoimmunity, and fever, but most men recover within 3–6 months. Vaccines do not impair male fertility.| David Lingenfelter, PhD
“COVID toes” are caused by a strong local interferon response to SARS-CoV-2, leading to vascular inflammation and microthrombosis, despite mild symptoms and negative tests.| David Lingenfelter, PhD
Long COVID causes mitochondrial collapse via viral proteins, immune dysregulation, and microvascular damage—triggering fatigue, muscle injury, and post-exertional malaise.| David Lingenfelter, PhD
Persistent SARS-CoV-2 in the gut may drive Long COVID via inflammation, barrier damage, and microbiome disruption—making gut-targeted therapies a key treatment path.| David Lingenfelter, PhD
COVID-19 causes kidney injury via direct viral attack and systemic inflammation. Severe cases lead to lasting damage and higher risk of chronic kidney disease.| David Lingenfelter, PhD
SARS-CoV-2 can damage the pancreas and thyroid via direct infection, inflammation, and autoimmunity—potentially leading to Type 1 Diabetes or permanent hypothyroidism.| davidlingenfelter.substack.com
Post-viral myocarditis evolves from direct viral damage to autoimmune-driven fibrosis, with imaging revealing lasting heart injury and guiding prognosis.| David Lingenfelter, PhD
SARS-CoV-2 leaves lasting epigenetic changes in lung cells, impairing repair and surfactant function—driving chronic inflammation, fibrosis, and long-term vulnerability.| David Lingenfelter, PhD
Long COVID stems from persistent SARS-CoV-2 reservoirs causing chronic T-cell exhaustion and dysfunction, leading to inflammation, autoimmunity, fatigue, & impaired immunity, driving diverse symptoms.| davidlingenfelter.substack.com
Long COVID is driven by neuroinflammation, autoimmunity, viral persistence, and vascular injury—requiring stratified, multi-modal, and precision-targeted therapies for effective treatment.| davidlingenfelter.substack.com
This is a guide for researchers on how to partner with an AI assistant, shifting their role from data gatherer to strategic analyst.| David Lingenfelter, PhD
Post-COVID cognitive deficits—especially in executive function and processing speed—can persist or worsen, driven by neuroinflammation and brain network damage, raising dementia risk.| davidlingenfelter.substack.com
Long COVID brain fog arises from two synergistic pathologies: a leaky blood-brain barrier and persistent microthrombosis, causing chronic inflammation and cerebral hypoperfusion.| davidlingenfelter.substack.com
SARS-CoV-2 has a unique S1/S2 furin site, but also shares a conserved S2' site with bat and pangolin viruses—key for infectivity and a target for broad-spectrum vaccines.| davidlingenfelter.substack.com
SARS-CoV-2 leaves lasting epigenetic changes that may dysregulate immunity, increasing reinfection and long COVID risk, though effects vary and IL-6 blockade may offer protection.| davidlingenfelter.substack.com
