Tumor-Derived Extracellular Vesicles Induce CCL18 Production by Mast Cells: A Possible Link to Angiogenesis

open access: yesCells, 2022
Mast cells (MCs) function as a component of the tumor microenvironment (TME) and have both pro- and anti-tumorigenic roles depending on the tumor type and its developmental stage. Several reports indicate the involvement of MCs in angiogenesis in the TME

CRISPR/Cas9-engineering of HMC-1.2 cells renders a human mast cell line with a single D816V-KIT mutation: An improved preclinical model for research on mastocytosis

open access: yesFrontiers in Immunology, 2023
The HMC-1.2 human mast cell (huMC) line is often employed in the study of attributes of neoplastic huMCs as found in patients with mastocytosis and their sensitivity to interventional drugs in vitro and in vivo.

Thymic Stromal Lymphopoietin Promotes MRGPRX2-Triggered Degranulation of Skin Mast Cells in a STAT5-Dependent Manner with Further Support from JNK

open access: yesCells, 2021
Thymic stromal lymphopoietin (TSLP) is released by epithelial cells following disturbed homeostasis to act as “alarmin” and driver of Th2-immunity. Aberrant TSLP expression is a hallmark of atopic diseases, including atopic dermatitis (AD).

Oncogenic D816V-KIT signaling in mast cells causes persistent IL-6 production

open access: yesHaematologica, 2020
Persistent dysregulation of IL-6 production and signaling have been implicated in the pathology of various cancers. In systemic mastocytosis, increased serum levels of IL-6 associate with disease severity and progression, although the mechanisms involved

Mastocytosis-derived extracellular vesicles deliver miR-23a and miR-30a into pre-osteoblasts and prevent osteoblastogenesis and bone formation

open access: yesNature Communications, 2021
Osteoporosis and bone disease are common in patients with systemic mastocytosis. Here, the authors show that extracellular vesicles released by neoplastic mast cells of the patients block osteoblast differentiation and bone mineralization when injected ...

Mast Cells [PDF]

open access: yesCurrent Gastroenterology Reports, 2010
Mast cells have been considered for many years to participate specifically in allergic reactions through the release of cytokines, chemokines, proteases, leukotrienes, and bioactive polyamines. Emerging roles for mast cells have been identified recently, which highlight their relevance in both innate and adaptive immunity.

Interleukin-33 Amplifies Human Mast Cell Activities Induced by Complement Anaphylatoxins

open access: yesFrontiers in Immunology, 2021
Both, aberrant mast cell responses and complement activation contribute to allergic diseases. Since mast cells are highly responsive to C3a and C5a, while Interleukin-33 (IL-33) is a potent mast cell activator, we hypothesized that IL-33 critically ...

The role of macrophage migration inhibitory factor in mast cell-stimulated fibroblast proliferation and collagen production. [PDF]

open access: yesPLoS ONE, 2015
Current clinical and translational studies have shown that mast cell plays a pivotal role in multiple fibrotic diseases including scleroderma. However, the lack of mature human mast cell culture model exhibits a major obstacle for further dissection of ...

Adult-onset mast cell activation syndrome following scombroid poisoning: a case report and review of the literature

open access: yesJournal of Medical Case Reports, 2021
Background Mast cells are closely associated with epithelium, serving as sentinels responsible for the recognition of tissue injury and coordination of the initial inflammatory response.
