Parasitic helminths induce the production of interleukin-4 (IL-4), which causes the expansion of virtual memory CD8 + T cells (T VM cells), a cell subset that contributes to the control of coinfection with intracellular pathogens. However, the mechanisms regulating IL-4–dependent T VM cell activation and expansion remain ill defined. Here, we used single-cell RNA sequencing of CD8 + T cells to identify pathways that control IL-4–dependent T VM cell responses. Gene signature analysis of CD8 + T cells identified a cell cluster marked by CD22, a canonical regulator of B cell activation, as a selective surface marker of IL-4–induced T VM cells. CD22 + T VM cells were enriched for interferon-γ and granzyme A and retained a diverse TCR repertoire while enriched in self-reactive CDR3 sequences. CD22 intrinsically regulated the IL-4–induced CD8 + T cell effector program, resulting in reduced responsiveness of CD22 + T VM cells and regulatory functions to infection and inflammation. Thus, helminth-induced IL-4 drives the expansion and activation of T VM cells that is counterinhibited by CD22.

The bone marrow microenvironment plays a crucial role in the development of multiple myeloma. As the disease progresses, malignant myeloma cells can evolve to survive outside the bone marrow. However, the processes underlying bone marrow independence and their consequences for immune control remain poorly understood. Here, we conducted single-cell and spatial multiomics analyses of bone marrow–confined intramedullary disease and paired breakout lesions that disrupt the cortical bone. These analyses revealed a distinct cellular microenvironment and architectural features of breakout lesions, characterized by extensive areas of malignant plasma cells interspersed with lesion-specific solitary natural killer and macrophage populations, as well as focal accumulations of immune cell agglomerates. Within these agglomerates, spatially confined T cell clones expanded alongside various immune cells, coinciding with the local genomic evolution of tumor cells. These analyses identify breakout lesions as a hotspot for tumor-immune cell interactions and diversification, representing a key event in myeloma pathogenesis.

Stem-like T cells are attractive immunotherapeutic targets in patients with cancer given their ability to proliferate and differentiate into effector progeny. Thus, identifying T cells with enhanced stemness and understanding their developmental requirements are of broad clinical and therapeutic interest. Here, we demonstrate that during acute infection, the transcriptional regulator inhibitor of DNA binding 3 (ID3) identifies stem-like T cells that are uniquely adapted to generate precursors of exhausted T (Tpex) cells in response to chronic infection or cancer. Expression of ID3 itself enables Tpex cells to sustain T cell responses in chronic infection or cancer, whereas loss of ID3 results in impaired maintenance of CD8 T cell immunity. Furthermore, we demonstrate that interleukin-1 (IL-1) family members, including IL-36β and IL-18, promote the generation of ID3+ T cells that mediate superior tumor control. Overall, we identify ID3 as a common denominator of stem-like T cells in both acute and chronic infections that is specifically required to sustain T cell responses to chronic stimulation.
干样T细胞具有增殖和分化为效应原的能力，是癌症患者极具吸引力的免疫治疗目标。因此，识别干性增强的T细胞并了解它们的发育要求具有广泛的临床和治疗意义。在这里，我们证明了在急性感染期间，DNA结合抑制因子3（ID3）能识别干样T细胞，这些细胞具有独特的适应能力，能在应对慢性感染或癌症时生成衰竭T（Tpex）细胞的前体。ID3本身的表达能使Tpex细胞在慢性感染或癌症中维持T细胞反应，而ID3的缺失会导致CD8 T细胞免疫力的维持受损。此外，我们还证明了白细胞介素-1（IL-1）家族成员，包括 IL-36β 和 IL-18，能促进 ID3+ T 细胞的生成，从而介导卓越的肿瘤控制。总之，我们发现 ID3 是急性和慢性感染中干细胞样 T 细胞的共同特征，它是维持 T 细胞对慢性刺激反应的特殊需要。

Trogocytosis is an exchange of membrane-associated molecules between cells that can either halt or boost immune responses. However, the mechanism that regulates trogocytosis in T cells and its consequences are not yet clear. Here, we demonstrate that T cells can exchange chimeric antigen receptors (CARs) by trogocytosis, thereby arming recipient T cells with the capacity to respond to tumor antigens by up-regulating proteins associated with a cytotoxic response and killing of target cells. We demonstrate that although trogocytosis is dependent on cell-cell contact, the exchange of a specific cell membrane protein does not require a cognate binding partner on the surface of recipient cells. Instead, the probability that a protein is exchanged by trogocytosis is determined by its transmembrane domain. This finding opens new avenues for modulating this process in CAR-T cells.

Our understanding of the meningeal immune system has recently burgeoned, particularly regarding how innate and adaptive effector cells are mobilized to meet brain challenges. However, information on how meningeal immunocytes guard brain homeostasis in healthy individuals remains limited. This study highlights the heterogeneous, polyfunctional regulatory T cell (Treg) compartment in the meninges. A Treg subtype specialized in controlling interferon-γ (IFN-γ) responses and another dedicated to regulating follicular B cell responses were substantial components of this compartment. Accordingly, punctual Treg ablation rapidly unleashed IFN-γ production by meningeal lymphocytes, unlocked access to the brain parenchyma, and altered meningeal B cell profiles. Distally, the hippocampus assumed a reactive state, with morphological and transcriptional changes in multiple glial cell types. Within the dentate gyrus, neural stem cells underwent more death and were blocked from further differentiation, which coincided with impairments in short-term spatial-reference memory. Thus, meningeal Tregs are a multifaceted safeguard of brain homeostasis at steady state.

Understanding how intratumoral immune populations coordinate antitumor responses after therapy can guide treatment prioritization. We systematically analyzed an established immunotherapy, donor lymphocyte infusion (DLI), by assessing 348,905 single-cell transcriptomes from 74 longitudinal bone marrow samples of 25 patients with relapsed leukemia; a subset was evaluated by both protein- and transcriptome-based spatial analysis. In acute myeloid leukemia (AML) DLI responders, we identified clonally expanded ZNF683+ CD8+ cytotoxic T lymphocytes with in vitro specificity for patient-matched AML. These cells originated primarily from the DLI product and appeared to coordinate antitumor immune responses through interaction with diverse immune cell types within the marrow microenvironment. Nonresponders lacked this cross-talk and had cytotoxic T lymphocytes with elevated TIGIT expression. Our study identifies recipient bone marrow microenvironment differences as a determinant of an effective antileukemia response and opens opportunities to modulate cellular therapy.

We systematically analyzed an established immunotherapy, donor lymphocyte infusion (DLI), by assessing 348,905 single-cell transcriptomes from 74 longitudinal bone marrow samples of 25 patients with relapsed leukemia; a subset was evaluated by both protein- and transcriptome-based spatial analysis. In acute myeloid leukemia (AML) DLI responders, we identified clonally expanded <i>ZNF683</i><sup>+</sup> CD8<sup>+</sup> cytotoxic T lymphocytes with in vitro specificity for patient-matched AML. These cells originated primarily from the DLI product and appeared to coordinate antitumor immune responses through interaction with diverse immune cell types within the marrow microenvironment. Nonresponders lacked this cross-talk and had cytotoxic T lymphocytes with elevated <i>TIGIT</i> expression. Our study identifies recipient bone marrow microenvironment differences as a determinant of an effective antileukemia response and opens opportunities to modulate cellular therapy.</div>","PeriodicalId":21734,"journal":{"name":"Science Immunology","volume":"10 103","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.science.org/doi/reader/10.1126/sciimmunol.adr0782","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
