The control of the specificity of CD4 T cells responses: thresholds, breakpoints and ceilings

Frontiers in Immunology, 2013
It has been known for over 25 years that CD4 T cell responses are restricted to a finite number of peptide epitopes within pathogens or protein vaccines. These selected peptide epitopes are termed immunodominant.

Nasal Epithelial Immune Signatures Are Associated With Age‐Dependent Asthma Trajectories in Early Life

Allergy, EarlyView.
Nasal epithelial transcriptomics identified three cytokine‐associated epithelial immune programs linked to childhood asthma phenotypes. Age‐associated epithelial polarization shifted from IFN/type‐17‐associated toward type‐2‐associated programs after 3 years of age.

Outflanking Immunodominance to Target Subdominant Broadly Neutralizing Epitopes

, 2018
A major obstacle to vaccination to antigenically variable viruses is skewing of antibody responses to immunodominant epitopes. For influenza virus hemagglutinin (HA), the immunodominance of the variable head impairs responses to the highly conserved stem.

Parallel detection of SARS‐CoV‐2 epitopes reveals dynamic immunodominance profiles of CD8+ T memory cells in convalescent COVID‐19 donors

Clinical & Translational Immunology, 2022
Objectives High‐magnitude CD8+ T cell responses are associated with mild COVID‐19 disease; however, the underlying characteristics that define CD8+ T cell‐mediated protection are not well understood.

Autoantibodies to Extracellular Erythrocyte Band 3 Epitopes Are Associated With Anemia in Plasmodium vivax Infection

American Journal of Hematology, Volume 101, Issue 10, Page 2592-2604, October 2026.
ABSTRACT Plasmodium vivax‐associated anemia is a multifactorial clinical outcome, in which the destruction of uninfected red blood cells (uRBCs) plays a major role in disease development and severity. Here, we identified autoantibody targets within the extracellular loops of Band 3 (B3), a major erythrocyte transmembrane protein.

Germinal Center Selection and Plasma Cell Differentiation

Immunological Reviews, Volume 342, Issue 1, September 2026.
ABSTRACT Germinal centers (GCs) are specialized microenvironments in which B cells undergo affinity maturation through iterative cycles of somatic hypermutation, proliferation and selection, generating antibodies with improved antigen‐binding properties.

A peptide filtering relation quantifies MHC class I peptide optimization [PDF]

, 2011
Major Histocompatibility Complex (MHC) class I molecules enable cytotoxic T lymphocytes to destroy virus-infected or cancerous cells, thereby preventing disease progression. MHC class I molecules provide a snapshot of the contents of a cell by binding to

Immunodomination of Serotype-Specific CD4+ T-Cell Epitopes Contributed to the Biased Immune Responses Induced by a Tetravalent Measles-Vectored Dengue Vaccine

Frontiers in Immunology, 2020
Dengue is an emerging mosquito-borne disease, and the use of prophylactic vaccines is still limited. We previously developed a tetravalent dengue vaccine (rMV-TDV) by a recombinant measles virus (MV) vector expressing envelope protein domain III (ED3 ...

Single Cell Multi‐Omics Revealing the Important Role of MR1 Mediated MAIT Cells in Maintaining Rejection for Liver Transplantation

Cell Proliferation, Volume 59, Issue 8, August 2026.
This multi‐omics study reveals the significant role of MAIT cells in liver transplant rejection. MAIT cells drive rejection in liver transplantation via the MR1 axis. Their absence reshapes T cell responses and clonal expansion, attenuating allograft injury.
