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 ]
A granuloma is an aggregation of macrophages (along with other cells) that forms in response to chronic inflammation.This occurs when the immune system attempts to isolate foreign substances that it is otherwise unable to eliminate. [1]
T h 2 cells and ILC2 cells secrete IL-4, IL-5 and IL-13. [1] [3] IL-4 further drives CD4+ T cell differentiation towards the T h 2 subtype and induces isotype switching to IgE in B cells. IL-4 and IL-13 stimulate trafficking of eosinophils to the site of inflammation, while IL-5 promotes both eosinophil trafficking and production. [2]

An immune-mediated inflammatory disease (IMID) is any of a group of conditions or diseases that lack a definitive etiology, but which are characterized by common inflammatory pathways leading to inflammation, and which may result from, or be triggered by, a dysregulation of the normal immune response. All IMIDs can cause end organ damage, and ...
These responses are characterized by periodic or chronic systemic inflammation, usually without the involvement of adaptive immunity. Autoinflammatory diseases are a separate class from autoimmune diseases; however, both are characterized by an immune system malfunction that may cause similar symptoms, such as rash, swelling or fatigue.
