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.
An artery is not like a nose. Or is it? Scientists at La Jolla Institute for Immunology (LJI) have discovered that immune cells in arteries can "sniff" out their surroundings and cause inflammation.
The lungs are exposed to microorganisms like viruses and bacteria from the moment of the first breath.
To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within.
New research from The University of Texas MD Anderson Cancer Center found that treatment with antihistamines, a commonly used allergy medication, was associated with improved responses to immune checkpoint inhibitors.
Scientists recently identified the therapeutic benefits to patients receiving mesenchymal stromal cell (MSC) therapy.
Macrophages are important cells of the immune system with numerous beneficial functions. However, macrophages also aggravate common diseases.
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have developed macrophage–tumor chimeric exosomes that co-activate the immune response and tumor microenvironment to support cancer immunotherapy.
Similar to how a spider traps its prey, the cells of the human immune system cooperate to trap and “eat” bacteria.
An immune signal promotes the production of energy-burning "beige fat," according to a new study publishing August 5th in the open-access journal PLOS Biology by Zhonghan Yang of Sun Yat-Sen University, Guangzhou, China, and colleagues.
A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.
In recent years, immunotherapy has revolutionized the field of cancer treatment. However, inflammatory reactions in healthy tissues frequently trigger side effects that can be serious and lead to the permanent discontinuation of treatment.
Researchers at the University of Turku, Finland, showed that the antibody treatment reactivates the immune defense in patients with advanced-stage cancer. The treatment alters the function of the body's phagocytes and facilitates extensive activation of the immune system.
UCLA life scientists have identified six "words" that specific immune cells use to call up immune defense genes -- an important step toward understanding the language the body uses to marshal responses to threats.
Chemotherapy has a damaging effect on hematopoietic stem and progenitor cells (HSPCs) in bone marrow. However, once chemotherapy ends, HSPCs regenerate, a process that has remained unknown--until now.
Oncotarget published "Cancer stem cells and macrophages: molecular connections and future perspectives against cancer" which reported that Cancer stem cells have been considered the key drivers of cancer initiation and progression due to their unlimited self-renewal capacity and their ability to induce tumor formation.
Sepsis can result when the body’s immune response to a specific infection gets out of control.
According to an analysis of data humans’ ability to combat diseases may largely depend on day-to-day circadian cycles than previously believed.
Systemic sclerosis is an autoimmune disease associated with inflammation and fibrosis, or scarring, that affects organs including the skin, heart, kidney and lungs.
In this interview, Dr. Shalin Naik speaks to AZoLifeSciences about his team's latest research that led to the discovery of a new step in the development of T and B cells that could help us to better understand leukemia.
Multiple sclerosis (MS) is an autoimmune disorder that develops as immune cells attack the nervous system. T cells are a critical part of our immune system, with a complex array of subtypes - some drive the autoimmune response, while others try to suppress it.
