Cytokine proteins are classified as chemokines according to behavior and structural characteristics. In addition to being known for mediating chemotaxis, chemokines are all approximately 8–10 kilodaltons in mass and have four cysteine residues in conserved locations that are key to forming their 3-dimensional shape.
Cytokines (/ ˈ s aɪ t ə k aɪ n /) [1] are a broad and loose category of small proteins (~5–25 kDa [2]) important in cell signaling. Due to their size, cytokines cannot cross the lipid bilayer of cells to enter the cytoplasm and therefore typically exert their functions by interacting with specific cytokine receptors on the target

An inflammatory cytokine is a type of cytokine (a signaling molecule) that is secreted from immune cells and certain other cell types that promotes inflammation. Inflammatory cytokines are predominantly produced by T helper cells ( T h ) and macrophages and involved in the upregulation of inflammatory reactions. [ 1 ]
Thomae's function: is a function that is continuous at all irrational numbers and discontinuous at all rational numbers. It is also a modification of Dirichlet function and sometimes called Riemann function. Kronecker delta function: is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise.
The IL-10 family is one of the important types of cytokines, that can stop the inflammation. In general. these cytokines have a helical structure of homodimers. [4] The difference that the members of IL-10 family have between each other is that they have various receptor-binding residues, which help with interaction with specific cytokine receptors. [5]
[6] [7] Pegfilgrastim is a successful example of this delivery system. Pegfilgrastim is the pegylated form of the granulocyte-colony stimulating factor (G-CSF) filgrastim. Pegfilgrastim stimulates production and release of neutrophils in patients who experience bone marrow toxicity after receiving myelosuppressive anticancer drugs or radiation.
Chemokine receptors are G protein-coupled receptors containing 7 transmembrane helices [5] that are found predominantly on the surface of leukocytes.Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features.
