Although largely confined to the airways, SARS-CoV-2 infection has been associated with sensory abnormalities that manifest in both acute and chronic phenotypes. To gain insight on molecular basis of these abnormalities, we used golden hamster model characterize compare effects influenza A virus (IAV) nervous system. We detected transcripts but no infectious material cervical thoracic spinal cord dorsal root ganglia (DRGs) within first 24 hours intranasal infection. SARS-CoV-2–infected hamsters exhibited mechanical hypersensitivity was milder prolonged compared observed IAV-infected hamsters. RNA sequencing analysis DRGs 1 4 days after suggested perturbations predominantly neuronal signaling animals as opposed type I interferon animals. Later, 31 infection, a neuropathic transcriptome emerged from animals, which coincided SARS-CoV-2–specific hypersensitivity. These data revealed potential targets for pain management, including binding protein ILF3, validated murine models. This work elucidates transcriptomic signatures triggered by may underlie short- long-term abnormalities.

Some patients remain unwell for months after "recovering" from acute COVID-19. They develop persistent fatigue, cognitive problems, headaches, disrupted sleep, myalgias and arthralgias, post-exertional malaise, orthostatic intolerance other symptoms that greatly interfere with their ability to function can leave some people housebound disabled. The illness (Long COVID) is similar myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) as well persisting illnesses follow a wide variety of infectious agents following major traumatic injury. Together, these are projected cost the U.S. trillions dollars. In this review, we first compare ME/CFS Long COVID, noting considerable similarities few differences.

This comparison highlights how strong evidence each abnormality, illness, helps set priorities future investigation. review provides current road map literature biology both illnesses.

A subgroup of patients infected with SARS-CoV-2 remain symptomatic over three months after infection. distinctive symptom long COVID is post-exertional malaise, which associated a worsening fatigue- and pain-related symptoms acute mental or physical exercise, but its underlying pathophysiology unclear. With this longitudinal case-control study (NCT05225688), we provide new insights into the malaise in COVID. We show that skeletal muscle structure lower exercise capacity patients, local systemic metabolic disturbances, severe exercise-induced myopathy tissue infiltration amyloid-containing deposits muscles worsen induction malaise. This highlights novel pathways help to understand suffering from other post-infectious diseases.

PASC highly heterogenous may be associated multisystem tissue damage/dysfunction including acute encephalitis, cardiopulmonary syndromes, fibrosis, hepatobiliary damages, gastrointestinal dysregulation, myocardial infarction, neuromuscular neuropsychiatric disorders, pulmonary damage, renal failure, stroke, vascular endothelial dysregulation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral proteins bind to host mitochondrial proteins, likely inhibiting oxidative phosphorylation (OXPHOS) and stimulating glycolysis. We analyzed gene expression in nasopharyngeal autopsy tissues from patients with disease 2019 (COVID-19). In samples declining titers, the virus blocked transcription of a subset nuclear DNA (nDNA)–encoded OXPHOS genes, induced microRNA 2392, activated HIF-1α induce glycolysis, immune defenses including integrated stress response. COVID-19, SARS-CoV-2 was no longer present, had recovered lungs. However, nDNA remained suppressed tissue heart and, lesser extent, kidney, liver, whereas host-immune defense pathways were activated. During early infection hamsters peak lung load, minimally perturbed but down-regulated cerebellum up-regulated striatum even though detected brain. mid-phase mice, starting recover mouse These data suggest that when titer first peaks, there is systemic response followed by suppression induction glycolysis leading deployment antiviral defenses. Even cleared function recovered, heart, lymph nodes impaired, potentially severe COVID-19 pathology.

Cognitive dysfunction is often reported in patients with post-coronavirus disease 2019 (COVID-19) syndrome, but its underlying mechanisms are not completely understood. Evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Spike protein or fragments released from cells during infection, reaching different tissues, including the CNS, irrespective of presence viral RNA. Here, we demonstrate brain infusion mice has a late impact on cognitive function, recapitulating post-COVID-19 syndrome. We also show neuroinflammation and hippocampal microgliosis mediate Spike-induced memory via complement-dependent engulfment synapses. Genetic pharmacological blockage Toll-like receptor 4 (TLR4) signaling protects animals against synapse elimination induced by infusion. Accordingly, cohort 86 who recovered mild COVID-19, genotype GG TLR4-2604G>A (rs10759931) associated poor outcome. These results identify TLR4 as key target to investigate long-term after COVID-19 infection humans rodents.
