Supplementation of the Probiotic LLH135 Reduces Oxidative Stress in a Model of Hemiparkinsonism

Behavioural Neurology, Volume 2025, Issue 1, 2025.
Oxidative stress and neuroinflammation are considered as the two main etiological reasons behind idiopathic Parkinson’s disease (PD). Nevertheless, the actual treatments are focused on improving motor symptoms by restoring dopamine (DA) presence, leaving said causes unattended.

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

Veterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Intracellular Mg2+ concentrations are differentially regulated in the sperm head and mid‐piece in acrosome reaction inducing conditions

The FASEB Journal, Volume 38, Issue 21, 15 November 2024.
Because Mg2+ complexes with ATP, changes in intracellular Mg2+ ([Mg2+]i), monitored with Mag‐520, reflect, in part, ATP levels. Mag‐520 allows the concomitant detection of [Mg2+]i and [Ca2+]i. [Mg2+]i increases under two conditions that reduce ATP: starvation and capacitation. Conversely, nutrient addition to starved sperm decrease Mag‐520 fluorescence.

Infiltration of immune cells to the brain and its relation to the pathogenesis of Alzheimer's and Parkinson's diseases

Journal of Neurochemistry, Volume 168, Issue 9, Page 2316-2334, September 2024.
The disruption of the neurovascular unit and the infiltration of the peripheral immune cells into the central nervous system are hallmarks of neurodegenerative diseases. However, so far, the participation of infiltrating cells in the progression of these diseases has not been completely defined.
