High-throughput sequencing of the memory T cell receptor repertoire and machine learning can predict robust antibody and CD4 T cell response to de novo hepatitis B vaccine.

Description of the transcriptional and clonal landscape of virus-specific CD4⁺ T cells in acute and chronic viral infections, and a new reference map to interpret CD4 T cell diversity across tissues and biological models.

Calcium-calcineurin signaling cascade drives the acquisition of both the phenotype of the most self-reactive naive CD4 T cells and their enhanced cell-intrinsic ability to commit into induced regulatory T cells upon activation.

CD4+ T cells responding to chronic lymphocytic choriomeningitis virus infection display transcriptional heterogeneity that is marked by both lineage-specific gene expression profiles and core gene expression programs that are upregulated and conserved across multiple distinct populations of T helper cells.

The results presented here indicate that IL-10-producing CD4⁺ T cells express genes associated with chronically activated T_H1-like cells, undergo clonal expansion, and inhibit antiviral T cell responses via the secretion of arginase-1, facilitating viral persistence in mice infected with MCMV.

Cytotoxic CD4 T lymphocytes are abundantly generated in T. cruzi-infected mice, predominantly infiltrate infected hearts, depend on T-cell intrinsic IL-18R/MyD88 signaling for expansion and their blood frequency correlates with the severity of chronic myocarditis in patients with Chagas disease.

Selective involvement of Arp2/3 complex subunit isoforms ARPC5 or ARPC5L governs the distinct actin polymerization events in the nucleus or cytoplasm of CD4 T cells that are triggerd by T cell activation or DNA replication stress.

Higher affinity for self-pMHC complexes and broader promiscuity for foreign-pMHC complexes imparts a fitness advantage within the CD4⁺ T cell compartment in older mice.

Identification and characterisation of proteins and processes regulated by HIV in primary human CD4+ T cells using an HIV reporter virus for one-step, antibody-free magnetic selection.

Histone deacetylase 3 is required for CD4+ T cells to downregulate two cholesterol efflux transport proteins, ABCA1 and ABCG1, for successful proliferation after antigenic stimulation.
