Purpose: We investigated sex-related brain metabolic differences in Amyotrophic Lateral Sclerosis (ALS) and healthy controls (HC).
Methods: We collected two equal-sized groups of male (m-ALS) and female ALS (f-ALS) patients (n = 130 each), who underwent 2-[F]FDG-PET at diagnosis, matched for site of onset, cognitive status and King's stage. We included 168 age-matched healthy controls, half female (f-HC) and half male (m-HC).
Blood and airway eosinophilia represent markers for the endotype-driven treatment of allergic asthma. Little is known on mechanisms that link eosinophils and airway epithelial cells before and after these cells are infiltrated by eosinophils during allergic response. Given that innate immune mechanisms, mainly mediated by epithelial-derived cytokines (IL-33, IL-25, TSLP), induce eosinophil-maturing/attractive substances, we thought to evaluate the crosstalk between eosinophils and airway epithelial cells in the context of IL-33-mediated allergic inflammation.

- Eosinophils, when activated by the alarmin IL-33, produce extracellular vesicles (EV) that show potential anti-tumor effects, contrasting with those activated by IL-5.
- Incorporating these IL-33-activated eosinophil-derived EV (Eo33-EV) into tumor cells leads to increased expression of genes that promote cell cycle arrest and reduces tumor growth and metastasis.
- RNA sequencing highlights that Eo33-EV are enriched with tumor suppressor genes and pathways that enhance an epithelial phenotype, indicating their potential role in cancer therapy through cell reprogramming.
