Extracellular vesicles released from melanoma cells constitutively expressing MHC class II promote immune evasion and cancer progression

The FEBS Journal, EarlyView.
Here, we report the role of extracellular vesicles (EVs) released from melanoma cells constitutively expressing MHC class II in the regulation of immune cell functions and melanoma metastasis. In particular, we observed an increased localization of HLA‐DRα, CAM receptors, PD‐L1, and STAT3 signaling proteins in the EVs.

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

The FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

The FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Salivary Microvesicle Methylome and Microbiome Profiles in Periodontitis: An Exploratory Study

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim Salivary microvesicles (MVs) are nanosized extracellular vesicles from the host and microbiota whose cargo may mirror the biological state of their parent cells. This cross‐sectional study aimed to explore the diagnostic power of host methylome and microbiome profiles of MVs in various periodontal disease states. Materials and Methods This

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

Mammalian cells in culture actively export specific microRNAs [PDF]

, 2009
The discovery of microRNAs (miRNAs) as a new class of regulators of gene expression has triggered an explosion of research, but has left many unanswered questions about how this regulation works and how it is integrated with other regulatory mechanisms ...

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Immunomodulatory effects of photodynamic therapy for skin cancer: Potential strategies to improve treatment efficacy and tolerability

Photochemistry and Photobiology, EarlyView.
Photodynamic therapy (PDT) is a nonscarring treatment modality that is widely used for skin cancers and early squamous precursor lesions. PDT was previously thought to work primarily by killing cancer cells directly (via apoptosis or necrosis). However, more recent work indicates that a significant mechanism for PDT is the stimulation of anti‐cancer ...

Possible involvement of keratinocyte‐derived microvesicle particles in human photosensitivity disorders

Photochemistry and Photobiology, EarlyView.
In this model, ROS generated by UVB result in PAFR agonists acting upon the PAFR resulting in MVP generation release via the enzyme aSMase. In photosensitivity, there are increased ROS, resulting in augmented PAF agonists and increased MVP release. This process can be blocked by aSMase inhibitors.
