Front Immunol 15:1340013. doi: 10.3389/fimmu.2024.1340013 PMID: 38384465

Objective: To examine how systemic inflammation, induced by intraperitoneal administration of lipopolysaccharide (LPS), affects the retina of male and female mice. The study also evaluates whether blocking the NLRP3 inflammasome and the extrinsic apoptosis pathway provides retinal protection.

Summary: Systemic LPS exposure leads to neuronal and sex-specific adverse effects in the mouse retina. These effects are mitigated by inhibiting the NLRP3 inflammasome and the extrinsic apoptosis pathway, highlighting their protective roles.

Matcham AC, Toma K, Tsai NY, Sze CJ, Lin PY, Stewart IF, Duan X (2024) Cadherin-13 Maintains Retinotectal Synapses via Transneuronal Interactions. J Neurosci 44(5):e1310232023. doi: 10.1523/JNEUROSCI.1310-23.2023 PMID: 38123991

Objective: To explore the role of Type II cadherins, particularly Cdh13, in the formation of specific retinotectal synapses.

Summary: Cdh13 is highly expressed in wide-field neurons of the superficial superior colliculus (sSC), and its removal from presynaptic retinal ganglion cells (RGCs) leads to a significant reduction in dendritic spines on postsynaptic wide-field neurons. Unlike αRGCs and On–Off Direction-Selective Ganglion Cells (ooDSGCs), Cdh13-expressing RGCs utilize distinct mechanisms to establish precise retinotectal connections.

Usage: Immunohistochemistry (1:500).

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°.
