    Functional proteomic atlas of HIV infection in primary human CD4+ T cells

    Adi Naamati et al.
    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.

    Calcium-mediated shaping of naive CD4 T-cell phenotype and function

    Vincent Guichard et al.
    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.

    Functionally specialized human CD4+ T-cell subsets express physicochemically distinct TCRs

    Sofya A Kasatskaya et al.
    Functional subsets of helper CD4+ T cells carry TCR repertoires with distinct features that are reproducible across donors and are partially acquired at the level of thymic selection.

    Targeting MYC dependency in ovarian cancer through inhibition of CDK7 and CDK12/13

    Mei Zeng et al.
    A multi-transcriptional CDKs inhibitor suppresses MYC and induces regression of ovarian tumors, indicating that targeting CDK7, 12, 13 with THZ1 may be an effective approach for treating MYC-dependent malignancies.

    Sepsis impedes EAE disease development and diminishes autoantigen-specific naive CD4 T cells

    Isaac J Jensen et al.
    Sepsis-induced numerical loss of naive autoantigen-specific CD4 T cells reduces host capacity to develop autoimmune immune disease, thereby demonstrating an intriguing relationship between infection and autoimmune disease.

    Cdc7 activates replication checkpoint by phosphorylating the Chk1-binding domain of Claspin in human cells

    Chi-Chun Yang et al.
    Cdc7 and CK1g1 independently and additively phosphorylate the Chk1-binding domain of claspin to activate replication checkpoint with differential contribution of each kinase in different cell types.

    Self-recognition drives the preferential accumulation of promiscuous CD4+ T-cells in aged mice

    Neha R Deshpande et al.
    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.

    HDAC3 restrains CD8-lineage genes to maintain a bi-potential state in CD4+CD8+ thymocytes for CD4-lineage commitment

    Rachael Laura Philips et al.
    CD4 lineage commitment requires HDAC3 to prevent premature upregulation of CD8 lineage genes during T cell development.

    CD40 is a major regulator of dendrite growth from developing excitatory and inhibitory neurons

    Paulina Carriba, Alun M Davies
    CD40-activated CD40L-mediated reverse signalling has strikingly opposite effects on the growth of excitatory and inhibitory neuron dendrites in the developing brain of mice.

    TGF-β reduces DNA ds-break repair mechanisms to heighten genetic diversity and adaptability of CD44+/CD24− cancer cells

    Debjani Pal et al.
    Phenotypic diversity and cell state transition (i.e., acquisition of a CD44+/CD24- cell state or exposure to TGF-beta) can spur intra-tumor genetic heterogeneity and contribute to acquired resistance.
