Neuronal guidance cues attract or repel axons and/or neurons and play important roles in the pathfinding of neuronal networks and the functioning of nervous system. Prominent among them are the families of ephrins, semaphorins, Slits and netrins and their cognate cell-surface receptors. Due to their biological significance, extensive research has been carried out in the last ten years or so. Angiogenesis is a cellular process of capillary sprouting and configuring of neovasculatures, which shares many developmental, anatomical, physiological and pathophysiological features with the neural counterparts. This review will summarize the emerging evidence indicating the common molecular mechanisms underlying both axon guidance (including neuronal migration) and angiogenesis for exquisite regulation of proper wiring of both systems.

Macroscale neuroimaging results have revealed significant differences in the structural and functional connectivity patterns of gyri and sulci in the primate cerebral cortex. Despite these findings, understanding these differences at the molecular level has remained challenging. This study leverages a comprehensive dataset of whole-brain in situ hybridization (ISH) data from marmosets, with updates continuing through 2024, to systematically analyze cortical folding patterns.

Netrin-1 (NTN1) is a laminin-related secreted protein involved in axon guidance and cell migration. Previous research has established a significant connection between NTN1 and nervous system development. In recent years, mounting evidence indicates that NTN1 also plays a crucial role in tumorigenesis and tumor progression.

Despite accounting for only ~0.001% of all neurons in the human brain, midbrain dopaminergic neurons control numerous behaviors and are associated with many neuropsychiatric disorders that affect our physical and mental health. Dopaminergic neurons form various anatomically and functionally segregated pathways.

Semaphorin 3A (Sema3A) is an axon guidance molecule, which is also abundant in the adult central nervous system (CNS), particularly in perineuronal nets (PNNs). PNNs are extracellular matrix structures that restrict plasticity. The cellular sources of Sema3A in PNNs are unknown.

Advancements in single-cell multimodal techniques have greatly enhanced our understanding of disease-relevant loci identified through genome-wide association studies (GWASs). To investigate the biological connections between the eye and brain, we integrated bulk and single-cell multiomic profiles with GWAS summary statistics for eight neuropsychiatric and five ocular diseases. Our analysis uncovered five latent factors explaining 61.
