Evaluation of Humoral and Cellular Responses in SARS-CoV-2 mRNA Vaccinated Immunocompromised Patients

Frontiers in Immunology, 2022
BackgroundImmunocompromised patients are at increased risk of severe COVID-19 and impaired vaccine response. In this observational prospective study, we evaluated immunogenicity of the BNT162b2 mRNA vaccine in cohorts of primary or secondary ...

Molecular changes associated with increased TNF-α-induced apoptotis in naïve (TN) and central memory (TCM) CD8+ T cells in aged humans

Immunity & Ageing, 2018
Background Progressive T cell decline in aged humans is associated with a deficiency of naïve (TN) and central memory (TCM) T cells. We have previously reported increased Tumor necrosis factor-α (TNF-α)-induced apoptosis in TN and TCM T cells in aged ...

Selective IgM Deficiency—An Underestimated Primary Immunodeficiency

Frontiers in Immunology, 2017
Although selective IgM deficiency (SIGMD) was described almost five decades ago, it was largely ignored as a primary immunodeficiency. SIGMD is defined as serum IgM levels below two SD of mean with normal serum IgG and IgA.

Evaluation of Humoral and Cellular Immune Responses to the SARS-CoV-2 Vaccine in Patients With Common Variable Immunodeficiency Phenotype and Patient Receiving B-Cell Depletion Therapy

Frontiers in Immunology, 2022
IntroductionSARS-CoV-2 vaccines’ effectiveness is not yet clearly known in immunocompromised patients. This study aims to assess the humoral and cellular specific immune response to SARS-CoV-2 vaccines and the predictors of poor response in patients with
