TIGIT regulates CD4+ T cell immunity against polymicrobial sepsis

open access: yesFrontiers in Immunology
BackgroundSepsis is one of the major causes of death and increased health care burden in modern intensive care units. Immune checkpoints have been prompted to be key modulators of T cell activation, T cell tolerance and T cell exhaustion. This study was designed to investigate the role of the negative immune checkpoint, T cell immunoglobulin and ITIM ...

Characterizing Stage‐Specific Cellular Dynamics and Microenvironmental Remodeling in Lung Adenocarcinoma by Single‐Cell RNA Sequencing

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
This study integrated early‐stage patient specimens with publicly available datasets encompassing non‐malignant lung tissues and advanced‐stage LUAD through single‐cell sequencing, revealing a dynamically remodeled tumor microenvironment characterized by a hypoxia‐adapted malignant subset (C5), immunosuppressive LGMN+ macrophages, STAT1‐driven ...

Promising New Anti‐TIGIT Agents: Stealthy Allies in Cancer Immunotherapy

open access: yesClinical and Translational Science
TIGIT (T cell immunoreceptor with immunoglobulin and tyrosine‐based inhibitory motif (ITIM) domain), Vstm3, and VSIG9, are newly recognized immunological checkpoints. They are prominently expressed on CD4+ and CD8+ T cells, tumor‐infiltrating lymphocytes

TIGIT acts as an immune checkpoint upon inhibition of PD1 signaling in autoimmune diabetes

open access: yesFrontiers in Immunology
IntroductionChronic activation of self-reactive T cells with beta cell antigens results in the upregulation of immune checkpoint molecules that keep self-reactive T cells under control and delay beta cell destruction in autoimmune diabetes.

CD27 and ICOS as Targets of PD‐1/PD‐L1 Signaling to Regulate Resident Memory CD8+ T‐Cell‐Mediated Pulmonary Protection and Pathology

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Here it is revealed that the costimulatory receptors CD27 and ICOS are essential for the long‐term maintenance of PD‐1high CD8+ TRM cells following influenza infection. PD‐L1 blockade enhances the proliferation and activation of these cells through Nur77 activation downstream of the CD27/ICOS signaling axis, thereby boosting host immunity against ...

MGMT unmethylation and high levels of CD47 and TIGIT indicate a poor prognosis in adult diffuse gliomas

open access: yesFrontiers in Immunology
IntroductionIn 2021, the World Health Organization published a new classification system for central nervous system tumors. This study reclassified the adult diffuse glioma (ADG) into astrocytoma, oligodendroglioma, and glioblastoma (GBM) according to ...

Crosstalk Between Intratumoral Microbes and Tumor Immunity: Implications for Tumor Therapy

open access: yesCancer Medicine, Volume 15, Issue 2, February 2026.
ABSTRACT Background Emerging studies indicate that microbes are present in tumor cells and immune cells. Intratumoral microbiota (ITM) constitute an important component of the tumor immune microenvironment (TIME) and have an important impact on tumor progression and treatment. Objective Through the general elaboration of ITM represented by bacteria and

Turning Cancer Immunotherapy to the Emerging Immune Checkpoint TIGIT: Will This Break Through the Limitations of the Legacy Approach?

open access: yesVaccines
The discovery of immune checkpoints (ICs) has pushed cancer treatment into the next era. As an emerging immune checkpoint, the TIGIT/CD155 axis inhibits the cytotoxicity of T and NK cells through multiple pathways.
