Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

Medical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.

Cell Type‐Specific Extracellular Vesicles in Mouse Brain: Proteomic Signatures Highlight Astrocytic GlialCAM Network and GPCR Enrichment

Glia, Volume 74, Issue 10, October 2026.
Cell type–specific EVs were isolated from mouse brain and profiled by proteomics. Each EV subtype exhibited proteomic signatures consistent with the specialized functions of its cell of origin. Astrocyte‐derived EVs (ADEVs) were enriched for the GlialCAM/MLC1 network and GPCRs.
