Liposomal Nanovaccine Containing α-Galactosylceramide and Ganglioside GM3 Stimulates Robust CD8⁺ T Cell Responses via CD169⁺ Macrophages and cDC1

Vaccines, 2021
Successful anti-cancer vaccines aim to prime and reinvigorate cytotoxic T cells and should therefore comprise a potent antigen and adjuvant. Antigen targeting to splenic CD169+ macrophages was shown to induce robust CD8+ T cell responses via antigen ...

CCL3 and IL‐7 Synergistically Enhance CAR‐T Efficacy in Solid Tumors

Advanced Science, EarlyView.
Synergistic delivery of CCL3 and IL‐7 by CAR‐T cells overcomes the immunosuppressive tumor microenvironment by enhancing cell infiltration, survival, and local immune reprogramming. This also establishes positive feedback that amplifies anti‐tumor activity and memory responses in both CAR‐T and endogenous T cells, presenting a robust therapeutic ...

Tumor‐Specific Delivery of CD28 siRNA via Lyso‐PC C‐16 Modified Lipid Nanoparticles Overcomes Anti‐PD‐1 Resistance by Remodeling Tumor Microenvironment

Advanced Science, EarlyView.
This study develops 16:0 LPC‐modified lipid nanoparticles (LPC‐LNPs) with cancer cell specificity by exploiting altered tumor lipid metabolism. LPC‐LNPs encapsulating Cd28 small interfering RNA (LPC‐LNP‐Cd28) knock down cancer cell CD28 without affecting T cells, inflame the tumor microenvironment, and overcome anti‐PD‐1 resistance.

CD4 + helper T cells endow cDC1 with cancer-impeding functions in the human tumor micro-environment

Nature Communications, 2023
The presence of classical type 1 dendritic cells (cDC1) positively influences prognosis in cancer, but their intricate networking with the various T cell types found in the tumour microenvironment is not fully appreciated. Here the authors show that cDC1

Targeting DNGR‐1 with Fangchinoline Elevates Dendritic Cell Antigen Cross‐Presentation‐Mediated Antitumor Immunity in Melanoma

Advanced Science, EarlyView.
Fangchinoline is identified as a small‐molecule DNGR‐1 modulator that enhances dendritic‐cell cross‐presentation of tumor antigens. By engaging DNGR‐1 and activating Syk–Nox2 signaling, it promotes phagosomal ROS, antigen escape, MHC‐I presentation, and CD8+ T‐cell priming, thereby strengthening antitumor immunity and sensitizing tumors to PD‐1 ...

Antigen Spreading via Localized Administration Enhances Adoptive TCR‐T Cell Therapy in Pancreatic Cancer

Advanced Science, EarlyView.
Cancer vaccines face limitations in pancreatic cancer due to insufficient tumor antigens. This ionic liquid ILvax via local tumor delivery triggers robust cDC1‐dependent systemic anti‐tumor immunity. It boosts endogenous CD8+ T cells and optimizes adoptive TCR‐T function, providing a promising synergistic therapeutic strategy.

Cdc1 Is Required for Growth and Mn2+ Regulation in Saccharomyces cerevisiae

Genetics, 1998
Abstract Cdc1 function was initially implicated in bud formation and nuclear division because cdc1(Ts) cells arrested with a small bud, duplicated DNA, and undivided nucleus. Our studies show that Cdc1 is necessary for cell growth at several stages of the cell cycle, as well as in pheromone-treated cells.

Essential role for Batf3-dependent dendritic cells in regulating CD8 T-cell response during SARS-CoV-2 infection.

PLoS ONE, 2023
SARS-CoV-2 infection elicits robust CD8 T-cell responses, yet the identity of the mechanisms playing dominant roles in initiating the virus-specific CD8 T-cell responses are largely unknown.

Eye‐Brain Neuroimmune Axis Enables Long‐Term Survival in Glioblastoma by Modulating Brain Immune Surveillance and Neuronal Excitability

Advanced Science, EarlyView.
The eye–brain neuroimmune axis triggers immune activation and disrupts pathological neuronal connectivity to extend glioblastoma survival. ABSTRACT As an anatomical extension of the central nervous system (CNS), the eye harbors rich neural and immune interfaces with the brain. However, the integrated immunological and neurological nexus between the eye

Profiling MHC II immunopeptidome of blood‐stage malaria reveals that cDC1 control the functionality of parasite‐specific CD4 T cells

EMBO Molecular Medicine, 2017
In malaria, CD4 Th1 and T follicular helper (TFH) cells are important for controlling parasite growth, but Th1 cells also contribute to immunopathology. Moreover, various regulatory CD4 T‐cell subsets are critical to hamper pathology.
