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.

Salt-purified seaweed compound suppresses inflammatory and allergic reactions

Food allergies affect an estimated 3%–4% of the global population, yet no definitive cure is currently available.

KAIST researchers develop NUDGE technology to steer cell fate

Which genes need to be controlled to guide a stem cell toward a desired cell type, or to modulate an immune cell's inflammatory response? A Korean research team has developed a general-purpose computational framework that identifies the key targets needed to steer a cell toward a desired state with a single temporary intervention, without permanently altering its genes.

SARS-CoV-2 protein ORF8 drives macrophage infection and lung inflammation

In the sickest COVID-19 patients, the SARS-CoV-2 virus doesn't just cause severe damage by directly infecting airway cells.

NUS scientists harness magnetic pulses to reprogram immune cells to fight breast cancer

Researchers from the National University of Singapore (NUS) have demonstrated an innovative approach for targeted breast cancer therapy using pulsed electromagnetic fields (PEMFs).

Single-cell atlas reveals key macrophage subtypes in myocardial infarction

Announcing a new article publication for BIO Integration. Myocardial infarction (MI) is characterized by extensive immune activation and dynamic remodeling of the cardiac microenvironment, in which myeloid cells play critical roles in regulating inflammation and tissue repair.

Could scorpion venom inspire new treatments for liver disease?

Scorpion venom peptides show promising anti-inflammatory, antiviral, analgesic, and immunomodulatory effects, with experimental evidence suggesting that some candidates could target pathways involved in chronic liver disease and viral hepatitis. The review highlights Kv1.3-blocking peptides and antiviral compounds as potential therapeutic leads, while emphasizing that limited hepatic efficacy data, poor pharmacokinetics, immunogenicity, and manufacturing challenges must be overcome before clinical translation.

High-energy tissues rely on macrophages to clear cellular waste

The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture), and brown fat (for heat production), each require a lot of energy and make a lot of waste. And that waste needs to be managed.

Dual-drug microneedle patch targets inflammation and fat browning

The worldwide obesity crisis has become a dominant public health crisis across the globe. Over 3 billion people worldwide currently suffer from obesity, and forecasts warn the number will rise above 4 billion by 2035, accounting for more than half the global population.

MXene-based hydrogel offers dual-action treatment for periodontitis

Periodontitis is a highly prevalent chronic inflammatory disease worldwide. It leads to periodontal tissue destruction, alveolar bone resorption, and ultimately tooth loosening and loss, severely impacting patients' oral function and quality of life.

Giving immunotherapy before surgery boosts brain tumor treatment success

A team from UNIGE and HUG has shown that administering cell immunotherapy before surgery to remove a brain tumor is significantly more effective than administering it afterwards.

Could the type of fiber children eat matter for their developing gut microbiome?

A recent study found that different dietary fibers can shape the composition and activity of the gut microbiome during early childhood, with xyloglucan, arabinoxylan, and pectin increasing short-chain fatty acid production in laboratory fermentation experiments. Some fibers also supported gut barrier measures and altered inflammatory responses, while observational data linked higher pectin intake with greater microbial diversity in young children.

Review outlines how SIRT3 protein regulates global metabolic disorders

A comprehensive review published in Engineering systematically outlines the regulatory capacity of silent information regulator 3 (SIRT3), a mitochondrial deacetylase termed the "head goose molecule", and its negentropic mechanism for intervening global metabolic disorders including type 2 diabetes, obesity, and steatotic liver disease.

Engineered immune cells help eliminate severe bacterial infections effectively

Severe bacterial infections remain a major global health challenge because antibiotics alone often fail when the host immune system becomes dysfunctional.

Dexamethasone calms lung inflammation without weakening core immune responses

Researchers from Trinity College Dublin and St. James's Hospital have shown that dexamethasone, a commonly prescribed anti-inflammatory steroid, can reduce harmful inflammation triggered by Mycobacterium avium without weakening the ability of human immune cells to control the infection.

Breast cancer co-opts the immune system to attract nerves that fuel tumor growth

New research from the University of Oklahoma demonstrates how an aggressive form of breast cancer co-opts the body's own immune system to attract nerves that fuel tumor growth.

Malaria infection causes permanent damage to the spleen immune cells

Macrophages formed in the bone marrow can only assume the function of embryonal phagocytes, or "scavenger cells," to a certain degree according to a study by the University of Bonn and the Peter Doherty Institute for Infection and Immunity at the University of Melbourne.

Blocking xenophagocytosis improves donor cell survival and interspecies organ generation

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, report researchers at Institute of Science Tokyo, Japan.

Too little or too much iodine may push immunity off balance

This narrative review finds that adequate iodine supports thyroid hormone signaling, leukocyte metabolism, antioxidant defenses, and antimicrobial activity in humans and domesticated mammals. Both deficiency and sustained excess may impair immunity or promote thyroid inflammation, but precise immune-specific intake thresholds remain uncertain.

Researchers identify immune cell receptor that drives organ aging process

We may age at different rates, but none of us escapes aging. A study in mice and in human cells by Stanford Medicine researchers pins much of the blame on a particular type of immune cell's increased inability, with advancing age, to gobble up another immune cell type.

Discovery of lung protein offers hope for pulmonary fibrosis

Pulmonary fibrosis is a deadly disease where scar tissue grows in the lungs, making breathing more difficult. Approximately 2,170 Australians are diagnosed annually with idiopathic pulmonary fibrosis (IPF), a form of the disease with no known cause and very few treatments.
