TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis

Advanced Science, EarlyView.
A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

Differences between naive and memory T cell phenotype in Malawian and UK adolescents: a role for Cytomegalovirus?

BMC Infectious Diseases, 2008
Background Differences in degree of environmental exposure to antigens in early life have been hypothesized to lead to differences in immune status in individuals from different populations, which may have implications for immune responses in later years.

Nicotinamide Metabolism Constrains Memory CD8+ T Cell Formation Through a Putative HS1BP3‐SIRT1‐FOXO3‐BCL6 Axis

Advanced Science, EarlyView.
ABSTRACT Memory T cells exhibit long‐term persistence, a defining feature that underpins durable clinical responses to adoptive immunotherapies. The mechanisms that integrate metabolic cues with transcriptional control of memory fate remain undetermined. Here, we identify HS1‐binding protein 3 (HS1BP3) is preferentially expressed in memory CD8+ T cells.

SynNotch Receptors for Visualizing Immunoreceptor Force Transmission and Downstream Signaling In Vivo

Advanced Science, EarlyView.
A mechanically activated SynNotch reporter platform enables detection of force transmission through receptors as they mediate immune cell interactions. Targeting CD40 on B cells and TCR on T cells records force‐induced reporter activation across 2D coculture, 3D organoid, and implanted in mice, which also reveal force‐amplification of immune receptor ...

Increased NFAT activity with dual CAR stimulation in CD19xCD22 CAR T-cells is associated with decreased exhaustion and improved survival

Journal for ImmunoTherapy of Cancer
Background Chimeric antigen receptor (CAR) T-cell therapy is effective in treating B-cell malignancies, however relapse due to lack of CAR persistence and antigen-modulated escape remains common. Multiple strategies to simultaneously target CD19 and CD22

Effect of ageing on CMV-specific CD8 T cells from CMV seropositive healthy donors

Immunity & Ageing, 2009
Background Ageing is associated with changes in the immune system with substantial alterations in T-lymphocyte subsets. Cytomegalovirus (CMV) is one of the factors that affect functionality of T cells and the differentiation and large expansions of CMV ...

Acquisition of antibody isotypes against Plasmodium falciparum blood stage antigens in a birth cohort. [PDF]

, 2010
Information on the period during which infants lose their maternally derived antibodies to malaria and begin to acquire naturally their own immune responses against parasite antigens is crucial for understanding when malaria vaccines may be best ...

Macrophage PABPC4‐SPP1 Axis Orchestrates Immunosuppression in Colorectal Cancer

Advanced Science, EarlyView.
In the CRC microenvironment, macrophage PABPC4 binds to the 3′UTR of SPP1 mRNA to stabilize its expression, thereby sustaining M2‐like immunosuppressive macrophage polarization. Concurrently, this axis suppresses CD8+ T cell effector functions via CD44 signaling, collectively fostering an immunosuppressive niche that drives tumor progression.

Macrophage Trogocytosis of Tumor Cells Drives the Immunosuppression of Tumor Microenvironment

Advanced Science, EarlyView.
Trogocytosis efficiency varies significantly among different tumor cells and is inversely related to their cortical stiffness; this efficiency dictates the extent of immunosuppression via upregulation of CXCL5 and Arg‐1, ultimately driving CD8+T cell exhaustion and tumor escape.

CD8α Structural Domains Enhance GUCY2C CAR-T Cell Efficacy

Cancer Biology & Therapy
Despite success in treating some hematological malignancies, CAR-T cells have not yet produced similar outcomes in solid tumors due, in part, to the tumor microenvironment, poor persistence, and a paucity of suitable target antigens.
