Biology of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and the humoral immunoresponse:a systematic review of evidence to support global policy-level actions and research
文献摘要：
Background:Both population-level epidemiological data and individual-level biological data are needed to control the coronavirus disease 2019(COVID-19)pandemic.Population-level data are widely available and efforts to combat CO VID-19 have generated proliferate data on the biology and immunoresponse to the causative pathogen,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).However,there remains a paucity of systemized data on this subject.Objective:In this review,we attempt to extract systemized data on the biology and immuno-response to SARS-CoV-2 from the most up-to-date peer-reviewed studies.We will focus on the biology of the virus and immunological variations that are key for determining long-term immunity,transmission potential,and prognosis.Data Sources and Methods:Peer-reviewed articles were sourced from the PubMed database and by snowballing search of selected publications.Search terms included:"Novel Coronavirus"OR"COVID-19"OR"SARS-CoV-2"OR"2019-nCoV"AND"Immunity"OR"Immune Response"OR"Antibody Response"OR"Immunologic Re-sponse".Studies published from December 31,2019 to December 31,2020 were included.To ensure validity,papers in pre-print were excluded.Results:Of 2 889 identified papers,36 were included.Evidence from these studies suggests early seroconversion in patients infected with SARS-CoV-2.Antibody titers appear to markedly increase two weeks after infection,followed by a plateau.A more robust immune response is seen in patients with severe CO VID-19 as opposed to mild or asymptomatic presentations.This trend persists with regard to the length of antibody maintenance.However,overall immunity appears to wane within two to three months post-infection.Conclusion:Findings of this study indicate that immune responses to SARS-CoV-2 follow the general pattern of viral infection.Immunity generated through natural infection appears to be short,suggesting a need for long-term efforts to control the pandemic.Antibody testing will be essential to gauge the epidemic and inform decision-making on effective strategies for treatment and prevention.Further research is needed to illustrate immunoglobulin-specific roles and neutralizing antibody activity.
