Look Who Is Talking: Extracellular Vesicles as Mediators of Intercellular and Interorgan Communication

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Extracellular vesicles (EVs) mediate intercellular and interorgan communication during both physiological and pathological conditions. EVs include exosomes, ectosomes, and apoptotic bodies and contain bioactive molecules. EVs are delivered to proximal cells or can travel in bodily fluids and reach distant organs, where they trigger a response from the ...

The Brain‐Gut Axis in Parkinson's Disease Pathology

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Exposure to environmental toxins induces gut dysbiosis, increases intestinal epithelial barrier permeability, immune activation, and oxidative stress, promoting α‐syn misfolding and propagation. Brainstem DMV neurons exhibit α‐syn pathology, dysregulating neuronal excitability and vagal control of GI functions.

Molecular Pathogenesis of Memory Impairment in Parkinson's Disease: An Exploration of Underlying Mechanisms

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aim Parkinson's disease (PD) is primarily known for its motor symptoms but is increasingly recognized for its substantial cognitive effects, particularly on memory. This narrative review aims to clarify the complex molecular mechanisms contributing to memory impairment in PD by integrating findings from both animal and clinical ...

Prnp Deletion Mitigates Muscle Fiber Type‐Specific Sarcopenia Induced by Prion Infection in Mice

Immunity, Inflammation and Disease, Volume 14, Issue 4, April 2026.
ABSTRACT Recent studies have shown that significant expression of PrPC protein is also present in skeletal muscle, and it plays a significant role in maintaining skeletal muscle homeostasis. Although the expression of PrPC in skeletal muscle has been clarified, the effects of PrPSc‐mediated prion protein infection on sarcopenia in mice and its ...

ADAM10‐Mediated Proteolytic Remodelling of Signalling and Adhesion Proteins on Brain Cell‐Derived Small Extracellular Vesicles

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
ABSTRACT Proteases are common components of extracellular vesicles (EVs), yet the extent and functional relevance of ongoing proteolytic activity on EV surfaces remain largely unexplored. Such activity could significantly influence EV function and identity, with likely implications for EV‐mediated signalling, recipient cell targeting, cargo delivery ...

Liquid–Liquid Phase Separation in Viral Infection and Immunology

MedComm, Volume 7, Issue 4, April 2026.
LLPS organizes viral replication and antiviral immunity. Viruses hijack LLPS to form replication factories and evade immune sensors, while hosts assemble LLPS‐driven signaling hubs (e.g., MAVS, RIG‐I, and SGs) to amplify interferon responses. Targeting these condensate interfaces offers novel therapeutic strategies against infectious diseases ...
