Research suggests molecular approaches to brain tumor treatment
...The new study examined the role of proteins called cytokines
in augmenting the amount of IL-13 receptor expressed by tumor cells. The use of these cytokines
may improve treatment of glioblastoma cells by increasing the levels of IL-13 receptor in brain tumo...

Newly discovered 'branding' process helps immune system cells pick their fights
.... T cells kill pathogens or produce molecules like cytokines
that stop their growth. Scientists have known for some time that a second class of innate immune system cells known as antigen-presenting cells helps T cells determine what to attack. They do this by displaying fragments of proteins they have picked...
Researchers discover novel pathway of inflammation that contributes to lung damage in CF patients
...iotics, such as pneumocystis. The investigation of cytokines
is also leading to better understanding of their role in inflammation in the lungs of patients with cystic fibrosis. Dr. Kolls said, "I think that if we can understand the inflammation processes, we can make an impact on their lives." Dr. Kolls and h...

are molecules that have destructive effects throughout the body.) "Periodontal disease increases the production of cytokines, but it has been demonstrated that vitamin D can suppress cytokine production, and possibly decrease the risk of periodontal...
New immune cell found to be a key to inflammatory diseases
...Although TH1 and TH2 are known to produce powerful cytokines
- such as interferon-gamma (IFN-g) and allergy-associated interleukin 4 (IL-4), respectively - they are not inflammatory or associated with production of IL-17, which sets off an errant immune response that results in tissue inflammation. Researchers...
High fat diet alters hepatic immune system in mice
