| TGF-β-driven CD103 expression on CD8+ T cells was reversed following TGF-β neutralization in vitro, implicating TGF-β in T cell tissue retention and impaired systemic immunity. [Cancer Cell] |

|
| The vector allowed for the delivery of a variety of genes to human T cells, as shown for interleukin-2 and a microRNA-based short hairpin RNA for the knockdown of the gene coding for haematopoietic progenitor kinase 1, a negative regulator of T-cell-receptor signaling.

|
|
| Using multiomics analysis of CD8+ T cell features across multiple patient cohorts and tumor types, investigators identified tumor niche–dependent exhausted and other types of hypofunctional CD8+ T cell states. [Science Translational Medicine] |
|
|
|
| Scientists generated human hypoimmune T cells with disrupted B2M, CIITA, and TRAC genes using CRISPR-Cas9 editing. In addition, CD47 and anti-CD19 CAR were expressed using lentiviral transduction. [Nature Communications] |
|
|
|
| Researchers reported that patients with the autoimmune vasculitis giant cell arteritis (GCA) had a defective CD155-CD96 immune checkpoint. Macrophages from patients with GCA retained the checkpoint ligand CD155 in the endoplasmic reticulum, and failed to bring it to the cell surface. [Cell Reports Medicine] |

|
|
| To capture disease heterogeneity and tumor microenvironment cues, the authors developed the first patient-derived Mantle cell lymphoma spheroids that recapitulated tumor oncogenic pathways and immune microenvironment in a multiplexed system that allowed easy drug screening, including immunotherapies. [Leukemia] |

|
|
| Scientists probed HLA-X-idiotype-T cell receptors (TCR) binding and designed enhanced-reactive pHLA-TCR antigens using an in silico mutagenesis approach which they functionally validated by cell proliferation assays and flow cytometry.

|
| In humans, splenic immunoglobulin (Ig) D+CD27+ B cells displayed higher AKT signaling than naive IgD+CD27− and memory IgD−CD27+ B cells, and developed in an AKT-dependent manner from their precursors in vitro. [Cell Reports] |
|
|
|
| Investigators showed that activated T cells from older adults contributed to inflammaging by releasing mitochondrial DNA into their environment due to an increased expression of the cytokine-inducible SH2-containing protein (CISH). [Nature Aging] |
|
|
|
|
| Scientists highlight the biology of anti-tumor immunity underlying response and resistance to immune checkpoint therapy (ICT), discuss efforts to address the current challenges with ICT, and outline strategies to guide the development of subsequent clinical trials and combinatorial efforts with ICT.

|
|
| The authors discuss recent progress in understanding how metabolic regulation relates to type 2 immunity firstly by considering specifics of metabolism within type 2 immune cells, and secondly by stressing how type 2 immune cells are integrated more broadly into the metabolism of the organism as a whole.

| SAB Biotherapeutics announced that the US FDA has granted Breakthrough Therapy Designation to SAB-176, an investigational therapeutic, for post-exposure prophylaxis for Type A and Type B influenza illness in high-risk patients, including those who have anti-viral resistant strains.
