A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Pioneering cell therapy offers hope for advanced liver disease

A new type of cell therapy shows promise as the first treatment for advanced liver disease, following results from a clinical trial.

Scientists reveal why common pancreatic precancer lesions rarely turn deadly

Spatial and single-cell analyses of human donor pancreata showed that PanIN epithelial cells gradually acquire cancer-like molecular features, while their surrounding stromal and immune environment remains closer to normal pancreatic tissue. The findings suggest that delayed or incomplete microenvironmental reprogramming may help explain why most PanIN lesions remain indolent rather than progressing to pancreatic cancer.

RNA regulator RBM15 linked to immunity, metabolism, and cancer progression

A newly published review article brings attention to the expanding role of RBM15, a critical regulator of RNA m6A methylation, in the development and progression of a wide range of diseases, including cancer, metabolic disorders, and cardiovascular conditions.

Early lung damage patterns uncovered in children with cystic fibrosis

Researchers have mapped how lung damage begins early in life for children with cystic fibrosis, providing new insights that will help reshape future care.

Scientists capture immune cells attacking live melanoma cells in real time

Scientists at the Garvan Institute of Medical Research have captured, for the first time, 'housekeeping' immune cells actively attacking and engulfing live melanoma cells – a discovery that could change the way we approach treatment for one of Australia's most common and deadly cancers.

New eye drop formulation shows promise for dry eye disease

Researchers at Baylor College of Medicine and Okayama University in Japan have developed and tested in mice a promising new eye drop formulation for treating dry eye disease.

Biomimetic nanocomposite hydrogel promotes tendon healing and tissue regeneration

The new system, termed KGN@PB@CM, combines several advanced elements. Prussian blue (PB) nanozymes act as potent reactive oxygen species (ROS) scavengers, while kartogenin (KGN)-a small molecule that promotes stem cell migration and tenogenic differentiation-is loaded onto the PB core.

Research offers clearer genetic blueprint of breast cancer variants

A study led by Dr Jason Pitt, Principal Investigator at the Cancer Science Institute of Singapore (CSI Singapore), has identified eight new "signatures" of DNA patterns (gains and/or losses) in breast cancer.

Gene panel predicts chemotherapy response in triple-negative breast cancer

Researchers at The University of Texas MD Anderson Cancer Center have characterized cancer cell-specific features in the tumor microenvironment (TME) of early-stage triple-negative breast cancer (TNBC) tissues, identifying specific macrophage subtypes associated with chemotherapy response.

Rhein protects against intestinal injury in severe acute pancreatitis

Severe acute pancreatitis (SAP) remains one of the most formidable challenges in gastrointestinal emergency medicine.

Scientists discover immune cell control switch to destroy fungal infections

Scientists at the University of East Anglia (UK) have contributed to discovering a "control switch" inside our immune cells that helps the body destroy dangerous fungal infections.

Study reveals immune differences between titanium and zirconia implants

Zirconia is widely regarded as a promising alternative to titanium for bone and dental implants because of its aesthetic advantages, biocompatibility, and potential to reduce metal ion release.

Cell swelling in macrophages may trigger stronger inflammatory immune responses

As part of the body's first line of defense against foreign invaders, macrophages play an integral role in the innate immune system.

Metabolic rewiring could help CAR-T cells fight solid tumors

This review explains how glucose scarcity, lipid disruption, amino acid deprivation, and toxic metabolites weaken CAR-T cells inside solid tumors. It highlights metabolic reprogramming as a promising strategy to improve CAR-T cell persistence, adaptability, and anti-tumor function.

Baylor researchers develop SAMENT method to map metastatic tumor niches

Researchers at Baylor College of Medicine and collaborating institutions developed a method that reveals the cellular makeup of tissues that support metastatic cancer growth, which is the primary cause of death for most patients with solid tumors.

Study identifies protein essential for repairing damage after inflammation

Whenever there is a wound or infection, the body produces an inflammatory response. This is the body's first line of defense, and macrophages — cells of the innate immune system — play a key role: first, they help eliminate pathogens and other infectious agents, and then they trigger the mechanisms that repair the damage caused during the inflammatory process.

Natural compound obakulactone shows therapeutic potential for rheumatoid arthritis

A new study published in Engineering reveals that obakulactone (OL), a natural tetracyclic triterpenoid isolated from Phellodendri cortex, exerts a therapeutic effect on rheumatoid arthritis (RA) by promoting the degradation of acyl coenzyme A thioesterase 1 (ACOT1) via the ubiquitin‒proteasome pathway and restoring the homeostasis of unsaturated fatty acids.

Targeting glutamine metabolism enhances CAR-macrophage cancer therapy

Tumor-associated macrophages (TAMs) within the tumor microenvironment (TME) exhibit significant metabolic dysregulation, which impairs their antitumor function.

Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

Study finds long COVID leaves a distinct immune signature in the blood

Researchers identified a small panel of inflammatory and neurology-related blood proteins that may help distinguish long COVID from recovery or no prior infection, while also showing that booster vaccination did not appear to worsen these protein responses in this cohort. The study also found that immune responses after reinfection differed from those seen after the first SARS-CoV-2 infection, suggesting altered long-term immune behavior in some previously infected individuals.
