#IgA dominates the early neutralizing antibody response to #SARS-CoV-2

Abstract Humoral immune responses are typically characterized by primary IgM antibody responses followed by secondary antibody responses associated with immune memory and comprised of of IgG, IgA and IgE. Here we measured acute humoral responses to SARS-CoV-2, including the frequency of antibody-secreting cells and the presence of SARS-CoV-2-specific neutralizing antibodies in the serum, saliva and broncho-alveolar fluid of 159 patients with COVID-19. Early SARS-CoV-2-specific humoral … Continue reading #IgA dominates the early neutralizing antibody response to #SARS-CoV-2

#Blood type #diets lack supporting evidence: a systematic review

Background: Diets that are based on the ABO blood group system have been promoted over the past decade and claim to improve health and decrease risk of disease. To our knowledge, the evidence to support the effectiveness of blood type diets has not previously been assessed in the scientific literature. Objective: In this current systematic review, published studies that presented data related to blood type … Continue reading #Blood type #diets lack supporting evidence: a systematic review
