Cytokine is a substance that is made by cells of the immune system. Some cytokines can boost the immune response and others can suppress it. Cytokines can also be made in the laboratory by recombinant DNA technology and used in the treatment of various diseases, including cancer.
The cytokine family including interleukin-2 and -15 (IL-2 and IL-15) started out in a primitive vertebrate species with three related cytokines IL-2, IL-15, and IL-15-like (IL-15L), all sharing binding capacity for receptor chain IL-15Rα. IL-15L was conserved in fishes, reptiles, and some mammals but lost in humans and mice.
There is an idea within the coronavirus research field that there is some kind of T cell abnormality in critically ill COVID-19 patients, but specific details have not yet been clarified. To shed light on the problem, a research collaboration based in Kumamoto University (Japan) has performed a genetic analysis of T cells from lung tissue of COVID-19 patients.
Bottom Line: Enrichment of the lungs with oral commensal microbes was associated with advanced stage disease, worse prognosis, and tumor progression in patients with lung cancer.
"Wound healing is one of the most complex biological processes," writes Professor Kazumitsu Sugiura and Dr Kenta Saito from Fujita Health University, Japan, in their article recently published in Nature's Scientific Reports.
Researchers from Kumamoto University, Japan have proposed that cellular senescence variations during the aging process could lead to control of health and onset of age-related diseases.
Individuals require enough action to remove offensive viruses or bacteria, but not so much that their body suffer a considerable damage.
COVID-19 remains stubbornly inconsistent. More than a million people have died and 35 million have been diagnosed, but a large fraction of people infected with the coronavirus--about 45%, according to recent estimates--show no symptoms at all.
Scientists from Emory Health Sciences have been observing an intense stimulation of immune cells in severe cases of COVID-19 disease. This activation of immune cells is similar to acute flares of systemic lupus erythematosus (SLE)—an autoimmune disease.
Broiler chicken producers the world over are all too familiar with coccidiosis, a parasite-borne intestinal disease that stalls growth and winnows flocks.
Loved or hated, the humble oat could be the new superfood for cancer patients as international research shows a diet rich in fiber could significantly reduce radiation-induced gut inflammation.
After an infection of the human body with a pathogen, a cascade of reactions will usually be set into motion.
The results obtained are encouraging and the researchers could make headway in a multifunctional cell therapy system to treat inflammatory bowel disease.
Different plants and their products contain “bioactive” components that can reduce human diseases.
A study conducted by researchers at São Paulo State University (UNESP) suggests that irisin, a hormone secreted from muscles in response to exercise, could have a therapeutic effect on COVID-19 patients.
New research at Washington University School of Medicine in St. Louis helps illuminate a surprising mind-body connection.
Allergy is one of the most common diseases in Europe, it is estimated that more than 150 million Europeans suffer from recurring allergies and by 2025 this could have increased to half of the entire European population.
A major percentage of COVID-19 cases have become so severe that hospital admissions have become mandatory for both monitoring and treatment.
For patients who receive a heart transplant in the near future, the old adage, "Good things come in small packages," may become words to live by.
There are memory cells that remember previously encountered pathogens and help to react quickly and strongly when exposed to them again.
Memory cells essentially recall formerly encountered pathogens and help respond strongly and rapidly when they are exposed to this foreign matter again.
