Dendritic cells (DCs) use effective mechanisms to combat antigens and to bring about adaptive immune responses through their ability to stimulate näive T cells. At present, four major cell types are categorised as DCs: Classical or conventional (cDCs), Plasmacytoid (pDCs), Langerhans cells (LCs), and monocyte-derived DCs (Mo-DCs). It was suggested that pDCs, CD1c+ DCs and CD141+ DCs in humans are equivalent to mouse pDCs, CD11b+ DCs and CD8α+ DCs, respectively. Human CD141+ DCs compared to mouse CD8α+ DCs have remarkable functional and transcriptomic similarities. Characteristic markers, transcription factors, toll-like receptors, T helpers (Th) polarisation, cytokines, etc. of DCs are discussed in this review. Major histocompatibility complex (MHC) I and II antigen presentation, cross-presentation and Th polarisation are defined, and the dual role of DCs in the tumour is discussed. Human DCs are the main immune cells that orchestrate the immune response in the tumour microenvironment.

Immunostimulatory effects of Heyndrickxia coagulans SANK70258.

Biosci Biotechnol Biochem

Department of Biological Science and Technology, Tokyo University of Science, 6-3-1 Niijuku, Katsushika-ku, Tokyo, Japan.

Here, we examined the immunomodulating effects of Heyndrickxia coagulans SANK70258 (SANK70258). Mouse splenocytes treated with γ-ray-irradiated SANK70258 produced higher levels of IFN-γ than those with 7 types of lactic acid bacteria. IFN-γ was mainly produced by NK cells, involving IL-12/IL-23, dendritic cells (DCs), and NFκB signaling.

Background: Existing research has shown that those ageing with severe mental illness face significant challenges in daily life. Attendance at community-based day centres (DCs) is offered to support daily structure and break isolation. However, little is known about the experiences of those receiving this type of support while transitioning into retirement age.

Copper-coordination driven brain-targeting nanoassembly for efficient glioblastoma multiforme immunotherapy by cuproptosis-mediated tumor immune microenvironment reprogramming.

Limited drug accumulation and an immunosuppressive microenvironment are the major bottlenecks in the treatment of glioblastoma multiforme (GBM). Herein, we report a copper-coordination driven brain-targeting nanoassembly (TCe6@Cu/TP5 NPs) for site-specific delivery of therapeutic agents and efficient immunotherapy by activating the cGAS-STING pathway and downregulating the expression of PD-L1. To achieve this, the mitochondria-targeting triphenylphosphorus (TPP) was linked to photosensitizer Chlorin e6 (Ce6) to form TPP-Ce6 (TCe6), which was then self-assembled with copper ions and thymopentin (TP5) to obtain TCe6@Cu/TP5 NPs.

Tumor whole-cell vaccines are designed to introduce a wide range of tumor-associated antigens into the body to counteract the immunosuppression caused by tumors. In cases of lymphoma of which the specific antigen is not yet determined, the tumor whole-cell vaccine offers distinct advantages. However, there is still a lack of research on an effective preparation method for the lymphoma whole-cell vaccine.

Dendritic cells (DCs) are specialized immune cells that play a crucial role in presenting antigens and activating cytotoxic T lymphocytes to combat tumors. The immune checkpoint receptor programmed cell death-1 (PD-1) can bind to its ligand programmed cell death-ligand 1 (PD-L1), which is expressed on the surface of cancer cells. This interaction suppresses T-cell activation and promotes immune tolerance.
