Cross-reactive mAbs largely target the more conserved S2 subunit on S-proteins and we identified a SARS-CoV-2 cross-neutralizing epitope that could facilitate vaccine design and Ab-based.

This may help understand comorbidity and cross-reactivity despite a distant evolutionary origin. They found that of the SARS-CoV-2 and common cold coronavirus fragments that were most similar (at least 67 genetic similarity) 57 showed cross-reactivity by memory T cells. There can be cross-reactivity between the immune system and the antigens of two different pathogens, or between one pathogen and proteins on non-pathogens, which in some cases can be the cause of allergies. They then tested them for cross-reactivity against a peptide pool from other coronaviruses. Comparisons of structural features suggest that the VBP scaffold from peanuts and tree-nuts can support cross-reactivity. In immunology, the definition of cross-reactivity refers specifically to the reaction of the immune system to antigens. The structure of the VBPs from cashew and pistachio was solved using solution-NMR. The IgE profiles did not correlate with diagnosis group. IgE binding peptides were highly prevalent in the VBP domains AH1.1, AO1.1, JR2.1, and PV3.1, but not in AO1.2, JR2.2, JR2.3, and PV3.2 nor the unstructured regions. Peptide microarrays were used to identify immunoglobulin E (IgE) epitopes from the N-terminus of the vicilin allergens Ara h 1, Ana o 1, Jug r 2, and Pis v 3 using serum from three patient diagnosis groups: monoallergic to either peanuts or cashew/pistachio, or dual allergic. Vicilin-buried peptides (VBPs) are an emerging family of food allergens whose conserved structural fold could mediate peanut/tree-nut co-allergy. Peanut and tree-nut allergies are frequently comorbid for reasons not completely understood. ![]()
