Interleukin 36 Receptor Antagonist
Interleukin 36 receptor antagonist (IL-36RA) is a member of the interleukin-36 family of cytokines. It was previously named Interleukin-1 family member 5 (IL1F5). The protein is known to inhibit the effects of Interleukin-36 cytokines ( IL-36α, IL-36β and IL-36γ) via competing with their receptor IL-36R/IL1RL2 and thereby inhibiting their proinflammatory effects. Roles in disease Mutations in the IL-36RN gene resulting in a decrease or production of defective IL-36RA protein have been shown to cause inflammatory skin diseases including generalised pustular psoriasis, acrodermatitis continua suppurativa Hallopeau (ACH) and acute generalized exanthematous pustulosis Acute generalized exanthematous pustulosis (AGEP) (also known as pustular drug eruption and toxic pustuloderma) is a rare skin reaction that in 90% of cases is related to medication administration.

Interleukin-36
Interleukin 36, or IL-36, is a group of cytokines in the Interleukin 1, IL-1 family with pro-inflammatory effects. The role of IL-36 in inflammatory diseases is under investigation. There are four members of the IL-36 family which bind to the IL-36 receptor (IL1RL2/IL-1Rrp2/IL-36 receptor dimer) with varying affinities. IL36A, IL36B, and IL36G are IL-36 receptor agonists. Interleukin 36 receptor antagonist, IL36RA is an IL-36 receptor Receptor antagonist, antagonist, inhibiting IL-36R signaling. The agonists are known to activate NF-κB, mitogen-activated protein kinases, Erk1/2 and C-Jun N-terminal kinases, JNK through IL-36R/IL-1RAcP, which targets the Interleukin 8, IL-8 promotor and results in Interleukin 6, IL-6 secretion and induces various proinflammatory mediators. Binding of the IL-36R agonists to IL-1Rrp2 recruits IL-1RAcP, activating the signaling pathway. IL-36Ra binds to IL-36R, preventing the recruitment of IL-1RAcP. Function IL-36 has been found to activate T cell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytokines
Cytokines are a broad and loose category of small proteins (~5–25 kDa) important in cell signaling. Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. Cytokines include chemokines, interferons, interleukins, lymphokines, and tumour necrosis factors, but generally not hormones or growth factors (despite some overlap in the terminology). Cytokines are produced by a broad range of cells, including immune cells like macrophages, B lymphocytes, T lymphocytes and mast cells, as well as endothelial cells, fibroblasts, and various stromal cells; a given cytokine may be produced by more than one type of cell. They act through cell surface receptors and are especially important in the immune system; cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and resp ...

IL36B
Interleukin-36 beta also known as interleukin-1 family member 8 (IL1F8) is a protein that in humans is encoded by the ''IL36B'' gene. Function The protein encoded by this gene is a member of the interleukin 1 cytokine family. Protein structure modeling indicated that this cytokine may contain a 12-stranded beta-trefoil structure that is conserved between IL1A (IL-A alpha) and IL1B Interleukin-1 beta (IL-1β) also known as leukocytic pyrogen, leukocytic endogenous mediator, mononuclear cell factor, lymphocyte activating factor and other names, is a cytokine protein that in humans is encoded by the ''IL1B'' gene."Catabolin" ... (IL-1 beta). This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. Two alternatively spliced transcript variants encoding distinct isoforms have been reported. References Further reading * * * * * * * * * * * * * {{gene-2-stub ...

IL36G
Interleukin-36 gamma previously known as interleukin-1 family member 9 (IL1F9) is a protein that in humans is encoded by the ''IL36G'' gene. Expression ''IL36G'' is well-expressed in the epithelium of the skin, gut, and lung. In the skin ''IL36G'' is predominantly expressed in epidermal granular layer keratinocytes with little to no expression in basal layer keratinocytes. Function The protein encoded by this gene is a member of the interleukin-1 cytokine family. This gene and eight other interleukin-1 family genes form a cytokine gene cluster on chromosome 2. The activity of this cytokine is mediated via the interleukin-1 receptor-like 2 (IL1RL2/IL1R-rp2/IL-36 receptor), and is specifically inhibited by interleukin-36 receptor antagonist, (IL-36RA/IL1F5/IL-1 delta). Interferon-gamma, tumor necrosis factor-alpha and interleukin-1 β (IL-1β) are reported to stimulate the expression of this cytokine in keratinocytes. The expression of this cytokine in keratinocytes can also be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IL1RL2
Interleukin-1 receptor-like 2 is a protein that in humans is encoded by the ''IL1RL2'' gene In biology, the word gene (from , ; "...

Generalised Pustular Psoriasis
Generalized pustular psoriasis (GPP) is an extremely rare type of psoriasis that can present in a variety of forms. Unlike the most general and common forms of psoriasis, GPP usually covers the entire body and with pus-filled blisters rather than plaques. GPP can present at any age, but is rarer in young children. It can appear with or without previous psoriasis conditions or history, and can reoccur in periodic episodes. Signs and symptoms GPP presents as pustules and plaques over a wide area of the body. It differs from the localized form of pustular psoriasis in that patients are often febrile and systemically ill. However, the most prominent symptom, as described in the ''Archives of Dermatology'', is "sheeted, pinhead-sized, sterile, sub-corneal pustules". The IPC roundtable adds that these pustules often occur either at the edges "of expanding, intensely inflammatory plaques" or "within erythrodermic skin". Causes Most cases of generalized pustular psoriasis present in patie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrodermatitis Continua Suppurativa Hallopeau
Acrodermatitis /ac·ro·der·ma·ti·tis/ is a childhood form of dermatitis selectively affecting the hands and feet and may be accompanied by mild symptoms of fever and malaise. It may also be associated with hepatitis B and other viral infections. The lesions appear as small coppery-red, flat-topped firm papules that appear in crops and sometimes in long linear strings, often symmetric. It is a diffuse chronic skin disease usually confined to the limbs, seen mainly in women in Northern, Central, and Eastern Europe, and characterized initially by an erythematous, oedematous, pruritic phase followed by sclerosis and atrophy. It is caused by infection with ''Borrelia burgdorferi''. __TOC__ Types Types include: * Acrodermatitis enteropathica * Acropustulosis ** Acrodermatitis chronica atrophicans ** Papular acrodermatitis of childhood ** Dermatitis repens Dermatitis repens (also known as Acrodermatitis continua, Acrodermatitis perstans, Pustular acrodermatitis, Acrodermatitis con ...

Acute Generalized Exanthematous Pustulosis
Acute generalized exanthematous pustulosis (AGEP) (also known as pustular drug eruption and toxic pustuloderma) is a rare skin reaction that in 90% of cases is related to medication administration. AGEP is characterized by sudden skin eruptions that appear on average five days after a medication is started. These eruptions are pustules, i.e. small red white or red elevations of the skin that contain cloudy or purulent material (pus).James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . The skin lesions usually resolve within 1–3 days of stopping the offending medication. However, more severe cases are associated with a more persistent disorder that may be complicated by secondary skin infections and/or involvement of the liver, lung, and/or kidney. Severe cutaneous adverse reaction (SCAR) disorders are regarded as the drug-induced activation of T cells which then initiate innate immune responses th ...
