New Mechanism Links Mitochondria Dysfunction to T Cell Exhaustion

The immune system's killer T cells do a commendable job of detecting and destroying cancer cells. But the harsh environment at the heart of tumors often saps them of their vitality, pushing them into a state of permanent lassitude called "terminal exhaustion."

Molecular Switch Links Mitochondrial Stress to T Cell Exhaustion

Cancer-fighting T cells do not simply "run out of energy." They are molecularly reprogrammed.

Research Shows Successful Recovery of Antigen-Specific T Cells in Mouse Models

Researchers at The Jackson Laboratory (JAX), in collaboration with the Massachusetts Institute of Technology (MIT), have developed the first bandage-like microneedle patch that can sample the body's immune responses painlessly from the skin. The device detects inflammatory signals within minutes and collects specialized immune cells within hours without the need for blood draws or surgical biopsies.

New Genetic Rules Guide Killer T Cell Fate

A multi-institutional study led by researchers at UNC Lineberger Comprehensive Cancer Center, the Salk Institute for Biological Studies, and UC San Diego has uncovered new genetic rules that determine how powerful immune cells-known as CD8 killer T cells-choose between becoming long-lasting, protective defenders or slipping into exhausted, dysfunctional states.

DNA Origami Vaccine Scaffolds Sharpen Immune Targeting Against HIV

One of the biggest hurdles in developing an HIV vaccine is coaxing the body to produce the right kind of immune cells and antibodies. In most vaccines, HIV proteins are attached to a larger protein scaffolding that mimics a virus.

New Research Reveals RFC's Dynamic Partnership in DNA Synthesis

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands.

Blood protein test helps spot hidden cancers in patients with vague symptoms

Plasma protein profiling offers a promising tool for cancer risk stratification in patients with non-specific symptoms, potentially reducing diagnostic delays.

Rigid Protein Molecular Rulers Enable Precise Control of Antibody Conformation

By extending a naturally rigid bacterial protein by 50% while preserving geometry and stability, the study introduces protein-based "molecular rulers" that could probe antibody shape, limit unwanted motion, and support safer, more effective antibody drug design.

Blocking Retinoic Acid Pathway Improves Dendritic Cell Anti-Tumor Function

Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.

Engineered EVs Offer a Modular and Clinically Adaptable Immune-Tolerance Platform

A research team at the Nano Life Science Institute (WPI-NanoLSI) and the Faculty of Medicine at Kanazawa University has developed a new class of engineered extracellular vesicles (EVs) capable of inducing antigen-specific regulatory T cells (Tregs), the immune cells that play a central role in suppressing excessive immune responses.
