CD137 is a costimulatory receptor expressed on natural killer cells, T cells, and subsets of dendritic cells. An agonistic monoclonal antibody (mAb) against CD137 has been used to reduce tumor burden or reverse autoimmunity in animal models and clinical...

BACKGROUND: Mass vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is on-going in the United States with vaccines approved for emergency use by the FDA. Each vaccine can induce spike-specific antibodies (Abs) with virus-neutralizing activities; however, the Fc-mediated...

Laboratory mice comprise an expeditious model for preclinical vaccine testing; however, vaccine immunogenicity in these models often inadequately translates to humans. Reconstituting physiologic microbial experience to specific pathogen-free (SPF) mice induces durable immunological changes that better recapitulate human immunity....

Fc-dependent effector functions are an important determinant of the in vivo potency of therapeutic antibodies. Effector function is determined by the combination of FcRs bound by the antibody and the cell expressing the relevant FcRs, leading to antibody-dependent cellular...

Despite the development and deployment of antibody and vaccine countermeasures, rapidly-spreading SARS-CoV-2 variants with mutations at key antigenic sites in the spike protein jeopardize their efficacy. The recent emergence of B.1.1.529, the Omicron variant1,2, which has more than 30...

In a pattern called immune imprinting, individuals gain the strongest immune protection against the influenza strains encountered earliest in life. In many recent examples, differences in early infection history can explain birth year-associated differences in susceptibility (cohort effects). Susceptibility...
