Calcium Sensing in Exocytosis

, 2012
Neurotransmitters, neuropeptides and hormones are released through regulated exocytosis of synaptic vesicles and large dense core vesicles. This complex and highly regulated process is orchestrated by SNAREs and their associated proteins.

Refractory Eczema as a Presenting Feature of Common Variable Immunodeficiency

JEADV Clinical Practice, EarlyView.
ABSTRACT Common variable immunodeficiency (CVID) is the most prevalent symptomatic inborn error of immunity (IEI) in adults. It presents with recurrent infections and non‐infectious complications, including autoimmunity, lymphoproliferation and dermatitis.

Nail Lichen Planus in Children ‐ Epidemiology, Pathogenesis, Clinical Presentation, and Treatment

JEADV Clinical Practice, EarlyView.
ABSTRACT Nail lichen planus (NLP) is a chronic inflammatory disorder that, while rare in children compared to adults, represents a significant cause of pediatric nail dystrophy that requires early recognition to prevent permanent scarring and nail loss.

Modulation of Cisplatin Sensitivity through TRPML1-Mediated Lysosomal Exocytosis in Ovarian Cancer Cells: A Comprehensive Metabolomic Approach

Cells
Background: The lysosome has emerged as a promising target for overcoming chemoresistance, owing to its role in facilitating the lysosomal sequestration of drugs.

miR‐9 Restricts Insulin Secretion by Targeting Rab34, Which Mediates Lysosomal Degradation of Proinsulin

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Insulin secretion is a complex, vesicular transport process. Rab34 is a key regulator of intracellular vesicle transport; however, its role in insulin secretion has not yet been reported. miRNA‐9 is vital for the development and progression of the diagnosis and treatment of type 2 diabetes. This study aimed to investigate whether miR‐9 targets

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

AGRN‐, LRP4‐, MUSK‐Related CMS: Clinical, Neurophysiological, Morphological, Genetic and Pathological Mechanisms

Muscle &Nerve, EarlyView.
ABSTRACT Congenital myasthenic syndromes (CMS) are inherited disorders caused by mutations in genes encoding proteins essential for neuromuscular junction (NMJ) function. Pathogenic variants have been identified in more than 35 genes, underscoring the complexity of synaptic biology and the wide range of mechanisms that can compromise neuromuscular ...

Lysosome Morphology, Exocytosis and Immunity [PDF]

, 2013
Many types of immune cells rely on secretory lysosomes to execute their function. These specialised organelles perform the catabolic function of conventional lysosomes and possess the added capacity to undergo regulated exocytosis.
