Re-evaluating the Role of Antibodies in Tuberculosis

Abstract

Tuberculosis (TB) is a disease found in every country on Earth. About a quarter of the global population is estimated to be infected with Mycobacterium tuberculosis, the causative agent of TB, with over 10 million new TB cases reported annually. Currently, TB ranks as the second leading infectious killer after COVID-19. Research to develop novel interventions against TB represents a global health priority. TB research over the last several years focused on cellular immune responses, while the humoral response was largely neglected. This mini-review discusses evidence supporting a protective role of antibodies in TB, and a potential role of antibodies in TB vaccines and diagnosis.
