The transmembrane receptor tyrosine kinase (KIT), encoded by KIT, and the KIT ligand, encoded by KITLG, play crucial roles in the control of physiological and pathological skin pigmentation. The binding of KITLG to KIT regulates the migration, proliferation, differentiation and survival of melanocytes, and regulates melanogenesis and melanosome transfer. KITLG⁄KIT, which triggers the Ras⁄MAPK signaling pathway, plays crucial roles in melanin synthesis. Read More

Goal Attainment Scaling is an assessment instrument to evaluate interventions on the basis of individual, patient-specific goals. The attainment of these goals is mapped in a pre-specified way to attainment levels on an ordinal scale, which is common to all goals. This approach is patient-centred and allows one to integrate the outcomes of patients with very heterogeneous symptoms. Read More

The purpose of this article is to study the involvement of inflammatory mast cells (MCs) in depression which may be inhibited by IL-37. We evaluate mast cells in depression on the basis of our previous experimental data, and using the most relevant studies reported in the literature. Dysfunction of mood, feelings, and thoughts is a major risk factor for several metabolic diseases and may influence the physiology of the body leading to depression. Read More

Mastocytosis is a rare disease characterized by clonal neoplastic proliferation of mast cells (MCs). It ranges from skin lesions as cutaneous mastocytosis (CM) which may spontaneously regress to highly aggressive neoplasms with multiorgan involvement corresponding to some aggressive systemic mastocytosis (ASM), mast cell leukemia (MCL), and/or mast cell sarcoma (MCS).There is increasing evidence of CD30 expression in neoplastic MCs of the bone marrow.

Mast cell activation disease typically presents as chronic multisystem polymorbidity of generally inflammatory ± allergic theme. Presently, treatment of the rare, cytoproliferative variant systemic mastocytosis employs empirically selected therapies to impede mast cell mediator production and action and, when necessary, inhibition of proliferation. Some tyrosine kinase inhibitors (TKIs) have been used successfully in uncommon cases of systemic mastocytosis not bearing that disease's usual imatinib-resistant KIT mutation. Read More

Aims: To identify the presence and geographical distribution of mast cell (MC) subtypes: MC (tryptase positive-chymase negative) and MC (tryptase positive-chymase positive) in bladder tissue.
Methods: Bladder tissue was obtained from patients with painful bladder syndrome/interstitial cystitis (n=14) and normal histology from University Hospital Southampton tissue bank. Sequential tissue slices were immunohistochemically stained for MC subtypes using anti-MC tryptase (for MC and MC) and anti-MC chymase (for MC). Read More

Mastocytosis is a rare disease which occurs in both children and adults, and it can manifest as a solitary or multiple skin lesions. Both can cause cutaneous or systemic symptoms. Because of the heterogeneity of clinical presentation of mastocytosis and its rare prevalence, it can be hard to suspect the mastocytosis at the first time. Read More

The Kit proto-oncogene was found as a consequence of the discovery of the feline v-kit sarcoma oncogene. Stem cell factor (SCF) is the Kit ligand and it mediates Kit dimerization and activation. The Kit receptor contains an extracellular segment that is made up of five immunoglobulin-like domains (D1/2/3/4/5), a transmembrane segment, a juxtamembrane segment, a protein-tyrosine kinase domain that contains an insert of 77 amino acid residues, and a carboxyterminal tail.

Aberrant expression of wild-type and mutant forms of the platelet-derived growth factor receptor (PDGFR) family of receptor tyrosine kinases has been implicated in various oncologic indications such as leukemias, gliomas, and soft tissue sarcomas. Clinically used kinase inhibitors imatinib and sunitinib are potent inhibitors of wild-type PDGFR family members, but show reduced binding to mutant forms. Here we describe compound 5 which binds to both wild-type and oncogenic mutant forms of PDGFR family members, and demonstrates both cellular and in vivo activity. Read More

The anaphylactoid reaction described follows cessation of ranitidine in a 19-year-old female with the disease cluster: mast cell activation syndrome, hypermobile Ehlers-Danlos syndrome and postural tachycardia syndrome. Anaphylaxis can give wide-ranging symptoms from rhinorrhoea and urticaria to tachycardia and system-wide, life-threatening, anaphylactic shock. Individuals with a disorder of mast cell activation can experience many such symptoms. Read More

Flushing is the subjective sensation of warmth accompanied by visible cutaneous erythema occurring throughout the body with a predilection for the face, neck, pinnae, and upper trunk where the skin is thinnest and cutaneous vessels are superficially located and in greatest numbers. Flushing can be present in either a wet or dry form depending upon whether neural-mediated mechanisms are involved. Activation of the sympathetic nervous system results in wet flushing, accompanied by diaphoresis, due to concomitant stimulation of eccrine sweat glands. Read More

Mastocytosis is a disorder resulting from an abnormal mast cell (MC) accumulation in tissues that is often associated with the D816V mutation in KIT, the tyrosine kinase receptor for stem cell factor. Therapies available to treat aggressive presentations of mastocytosis are limited, thus exploration of novel pharmacological targets that reduce MC burden is desirable. Since increased generation of the lipid mediator sphingosine-1-phosphate (S1P) by sphingosine kinase (SPHK) has been linked to oncogenesis, we studied the involvement of the two SPHK isoforms (SPHK1 and SPHK2) in the regulation of neoplastic human MC growth.

Background: Cytokine interleukin (IL) 31 has emerged as an important component of allergic and inflammatory diseases associated with pruritus, such as atopic dermatitis (AD) and mastocytosis. Mast cells (MC) are stimulated by allergic and nonallergic triggers, and play a critical role in such diseases by secreting histamine and tryptase as well as cytokines and chemokines. IL-33 has been reported to augment MC responses, but its effect on secretion of IL-31 is not known. Read More
