The epsilon toxin from Clostridium perfringens stimulates calcium-activated chloride channels, generating extracellular vesicles in Xenopus oocytes.

The epsilon toxin (Etx) from Clostridium perfringens has been identified as a potential trigger of multiple sclerosis, functioning as a pore-forming toxin that selectively targets cells expressing the plasma membrane (PM) myelin and lymphocyte protein (MAL). Previously, we observed that Etx induces the release of intracellular ATP in sensitive cell lines. Here, we aimed to re-examine the mechanism of action of the toxin and investigate the connection between pore formation and ATP release.

Differential response of IgM and IgG memory B cell populations to CD40L: insights of T cell - memory B cell interactions.

Memory B cells (mBCs) are characterized by their long-term stability, fast reactivation, and capability to rapidly differentiate into antibody-secreting cells (ASCs). However, the role of T cells in the differentiation of mBCs, in contrast to naive B cells, remains to be delineated. We study the role of T cells in mBC responses, using CD40L stimulation and autologous T-B co-cultures.

ELIXIR and Toxicology: a community in development.

Toxicology has been an active research field for many decades, with academic, industrial and government involvement. Modern omics and computational approaches are changing the field, from merely disease-specific observational models into target-specific predictive models. Traditionally, toxicology has strong links with other fields such as biology, chemistry, pharmacology and medicine.

Sustainability capacity of a vegetable gardening intervention for cancer survivors.

Background: Health behavior interventions, especially those that promote improved diet and physical activity, are increasingly directed toward cancer survivors given their burgeoning numbers and high risk for comorbidity and functional decline. However, for health behavior interventions to achieve maximal public health impact, sustainability at both the individual and organizational levels is crucial. The current study aimed to assess the individual and organizational sustainability of the Harvest for Health mentored vegetable gardening intervention among cancer survivors.

Manifestations of anxiety and coping strategies in patients with metastatic lung cancer and their family caregivers: a qualitative study.

Advanced non-small cell lung cancer (NSCLC) is common, deadly, and associated with impairing anxiety for patients and caregivers who often co-experience similar symptoms that can vary together over time. We aimed to discover themes as to how NSCLC patients and caregivers express and cope with anxiety. Semi-structured interviews of patient-caregiver dyads ( = 21), coded using NVivo Software.
