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.
Macrophages, a type of white blood cell, defend the body by engulfing and digesting foreign particles, such as bacteria, viruses, and dead cells.
Researchers from Niigata University and Kyoto Prefectural University have revealed that small vesicles, around 100 nm in size, released by intestinal bacteria induce immune activation and progression of liver cirrhosis, as well as reduction of serum albumin level, subsequently leading to edema and ascites.
Carbon nanotubes (CNTs) are novel nanomaterials with potential uses in a variety of sectors. However, the harm they represent to people is unknown, and studies have revealed that multiwalled CNTs cause an immune response in mice.
Therapeutics that use mRNA-;like some of the COVID-19 vaccines-;have enormous potential for the prevention and treatment of many diseases.
M1 and M2 are activated macrophages that protect our immune system and maintain homeostasis.
A subset of white blood cells, known as myeloid cells, can harbor HIV in people who have been virally suppressed for years on antiretroviral therapy, according to findings from a small study supported by the National Institutes of Health.
To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code.
The removal of obsolete and damaged cell components by the body is crucial for fighting diseases like tuberculosis (TB), which establish themselves inside human cells, according to researchers from the Francis Crick Institute.
Most immunotherapies that aim to increase T cell activity are ineffective in treating estrogen receptor-positive (ER+) breast cancer. A new study of invasive ER+ breast cancers led by researchers at the University of Pittsburgh School of Medicine implies that targeting a different type of immune cell called macrophages may be a more effective approach.
Most immunotherapies, which aim to boost T cell activity, work poorly in treating estrogen receptor-positive (ER+) breast cancer.
A new study shows for the first time a connection between a mitochondrial metabolite and the activation of an inflammatory response.
For almost 140 years, the origin and behavior of an enigmatic cell type inside lymph nodes, called a tingible body macrophage, has remained a mystery.
Metabolic engineering is a field of plant biotechnology that seeks to genetically modify plant metabolic pathways to generate plant varieties with improved health benefits.
Thanks to a new prognostic method for detecting cancers including cancer of the large intestine, doctors could provide clearer disease prognoses and predict which patients will respond best to immunotherapy.
Damaged protein clusters in the brain are a hallmark of many neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and others. Although they have made significant efforts, scientists have only partially succeeded in finding treatments for these conditions by removing these toxic clusters.
The Black Death, which wiped off up to 50% of the European population in less than five years, was the single-worst mortality catastrophe in recorded history.
The method correctly categorizes macrophage states, which is crucial since these cells can alter their behavior and function as either pro- or anti-inflammatory agents during an immune response.
Researchers from the Monash Biomedicine Discovery Institute have demonstrated how the common fungus Candida albicans evades immune responses using newly discovered imaging technologies. The researchers claim that this involves a fungus that can shape-shift in an “alien-like” manner to escape immune cells.
Cedars-Sinai Cancer Center scientists found that cancerous tumors known as soft-tissue sarcomas generate a protein that changes immune cells from tumor attacking to tumor-promoting.
Professor Zi-Bing Jin is in charge of this research (Beijing Institute of Ophthalmology, Beijing Tongren Eye Center, Beijing Tongren Hospital, and Capital Medical University). He has spent the last decade working on retinal organoids, which can accurately mimic retinal development.
