Matynia A, Recio BS, Myers Z, Parikh S, Goit RK, Brecha NC, Pérez de Sevilla Müller L (2024) Preservation of intrinsically photosensitive retinal ganglion cells (ipRGCs) in late adult mice: Implications as a potential biomarker for early onset ocular degenerative diseases. Invest Ophthalmol Vis Sci 65(1):28. doi: 10.1167/iovs.65.1.28 PMID: 38224335

Objective: To assess the preservation of intrinsically photosensitive retinal ganglion cells (ipRGCs) in late adult mice and evaluate their potential as biomarkers for early onset ocular degenerative diseases.

Summary: This study investigates the stability of ipRGC morphology and function in mice aged 6 to 12 months, revealing that ipRGCs maintain their dendritic complexity and associated behavioral functions, such as pupillary light reflex and contrast sensitivity, during this period. These findings suggest that the consistent preservation of ipRGCs in late adulthood may serve as a valuable biomarker for early detection of ocular degenerative diseases, including Alzheimer’s, Parkinson’s, and diabetes.

Usage: Whole mount retinas were incubated with Anti-Melanopsin (AB-N39) at 1:1000 for 7 days at 4°C.

Liu H, Xue Y, Chen L (2022) Angiotensin II increases the firing activity of pallidal neurons and participates in motor control in rats. Metab Brain Dis 38:573-587. doi: 10.1007/s11011-022-01127-w PMID: 36454502

Objective: To investigate the functions of angiotensin II (Ang II)/angiotensin subtype 1 receptor (AT1R) on the globus pallidus neurons of both normal and Parkinsonian rats.

Summary: The authors conclude that pallidal Ang II/AT1R alleviated Parkinsonian motor deficits by activating globus pallidus neurons. This provides a rationale for further investigations into the potential of Ang II for treating motor disorders originating from the basal ganglia.

Usage: Coronal Sections (40 μm) containing the globus pallidus were blocked with 5% BSA and 0.3% Triton X-100 in PBS for 45 min and subsequently incubated with AT1R antibody (AB-N27AP) for 48 h at 4°.

Antioxidants (Basel) 11(10):2023. doi: 10.3390/antiox11102023 PMID: 36290746

Objective: To investigate the efficacy of aerobic exercise training (AET) in the prevention of dyslipidemia, insulin resistance (IR), and atherogenesis induced by severe low-sodium (LS) diet.

Summary: AET counteracts the deleterious effects of chronic LS diet in atherogenesis by reducing peripheral insulin resistance, lipid infiltration, carboxymethyllysine, receptor for advanced glycation end products, 4-HNE, and AT1 receptor in the intima-media of the brachiocephalic trunk in LDL receptor knockout mice.
