Lymph nodes may become discolored and inflamed with the presence of tattoo pigments, but discoloration and inflammation are also visual indicators of melanoma; consequently, diagnosing melanoma in a patient with tattoos is made difficult, and special precautions must be taken to avoid misdiagnoses.

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 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 ]
Inflammation is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and initiate tissue repair.
Inflammasomes are cytosolic multiprotein complexes of the innate immune system responsible for the activation of inflammatory responses and cell death. [1] [2] They are formed as a result of specific cytosolic pattern recognition receptors (PRRs) sensing microbe-derived pathogen-associated molecular patterns (PAMPs), damage-associated molecular patterns (DAMPs) from the host cell, or ...
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]
Schwann cell antigen Neuritis, paralysis: Hashimoto's thyroiditis [2] Thyroglobulin antigen Hypothyroidism, hard goiter, follicular thymitis Inflammatory bowel disease [2] Enteric microbiota and/or self antigens Hyperactivation of T-cells, cytokine release, recruitment of macrophages and other immune cells, inflammation Multiple sclerosis [2]
[2] [3] This immunologically distinct type of urticaria is considered autoimmune because the immune system, which normally protects the body from foreign organisms, mistakenly attacks the body's own cells, causing inflammation and other symptoms. [4] The condition is chronic, meaning it persists for more than six weeks, and can last for many ...
