These are an important type of proteins which play role in cell signalling. These are released from different cells. Some types of cytokines are chemokines, interferons, interlukins, lymphokines and the tumor necrosis factor. Cytokines are also produced by immune cells such as the macrophages, B-lymphocytes, T-lymphocytes and the mast cells. These proteins generally act by binding to different receptors and thus are important in the immune system
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
