Related StoriesIn the context of the recent pandemic, the memory T cells were able to detect many fragments of spike and non-spike regions of SARS-CoV-2. This observation was based on epitope similarities against a peptide pool of other coronaviruses. Due to pre-existing memory cells, some individuals experienced mild or moderate symptoms while others experienced severe infections.
About the Study In a recent Frontiers in Immunology journal study, scientists analyzed how SARS-CoV-2 monoclonal antibodies interacted with different pathogens and vaccines, especially DTaP. Additionally, the cross-reactivity between SARS-CoV-2 proteins and common foods that are consumed daily was determined. This is important because when undigested food antigens enter the circulation system, they produce food-specific antibodies.
Study Findings SARS-CoV-2 spike protein-specific antibodies were found to react most with the DTaP vaccine and, to a lesser degree, with E. faecalis bacteria, which is a common human gut microbe. A lesser reaction was observed against EBV Ab to Early Antigen D , EBV-Nuclear Antigen and B. burgdorferi. No reaction was observed against BCG, measles, E. coli CdT, EBV Viral Capsid Antigen Antibody , and Varicella-zoster virus .

Long-term neuromuscular consequences of SARS-Cov-2 and their similarities with myalgic encephalomyelitis/chronic fatigue syndrome: results of the retrospective CoLGEM study - Journal of Translational MedicineBackground Patients with long-COVID often complain of continuous fatigue, myalgia, sleep problems, cognitive dysfunction, and post-exertional malaise. No data are available on EMG recording of evoked myopotentials (M-waves) or exercise-induced alterations in long-COVID patients, providing evidence of muscle membrane fatigue. Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) develops in more than half of patients after an infectious disease, particularly viral diseases. A large proportion (around 70%) of these patients have neuromuscular disorders with M-wave alterations during and after exercise. Our hypothesis was that M-wave alterations would be also found in long-COVID patients, in association with neuromuscular symptoms, similar to ME/CFS. Methods This retrospective observational ColGEM (Covid LonG Encéphalomyelite Myalgique) study compared 59 patients with long-COVID and 55 ME/CFS patients with a history of severe infection who presented before the COVID pandemic. All of these patients underwent the same protocol consisting of a questionnaire focusing on neural and neuromuscular disorders and M-wave recording in the rectus femoris muscle before, during, and 10 min after a progressive cycling exercise. Maximal handgrip strength (MHGS) and maximal exercise power were also measured. The frequency of symptoms and magnitude of M-wave changes in the two groups were compared using non-parametric and parametric tests. Results The frequency of fatigue, myalgia, sleep problems, cognitive dysfunction, and post-exertional malaise as well as the magnitude of exercise-induced M-wave alterations were the same in the two groups. By contrast, digestive problems were less present in long-COVID. M-wave alterations were greater in ME/CFS patients as in those with long-COVID when the highest muscle strength and highest exercise performance were measured. Conclusions These high clinical and biological similarities between long-COVID and ME/CFS support the hypothesis that S
