    Helminth Derived Factors Inhibit Neutrophil Extracellular Trap Formation and Inflammation in Bacterial Peritonitis

    Scientists reported that helminth parasite excretory/secretory factors termed as parasitic ligands inhibited ROS-induced NETs by blocking the activation of nonselective calcium permeable channel transient receptor potential melastatin 2.

    Glycan Reactive Anti-HIV-1 Antibodies Bind the SARS-CoV-2 Spike Protein but Do Not Block Viral Entry

    Researchers reported that antibodies that displayed high levels of cross-reactivity with the SARS-CoV-2 spike, were incapable of neutralizing pseudoviruses expressing SARS-CoV-2 spike proteins and were unlikely to mediate ADE via FcγRII receptor engagement.

    Insights from Myalgic Encephalomyelitis/Chronic Fatigue Syndrome May Help Unravel the Pathogenesis of Post-Acute COVID-19 Syndrome

    Investigators summarize what is known about the pathogenesis of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and of acute COVID-19, and speculate that the pathogenesis of post-COVID-19 syndrome in some people may be similar to that of ME/CFS.
