Summary: Adult neurogenesis refers to the ability of specialized cells in the postnatal brain to produce new functional neurons and integrate them into the existing neuronal network. It is important for various processes, including memory, learning, anxiety responses, and is also involved in neurodegenerative and psychiatric disorders. This study aims to expand the understanding of the neurogenic niches in the brain of Scyliorhinus canicula and identify actively proliferating cells in different brain areas.

Summary: This study describes the isolation and identification process of Vibrio species following a mortality event in juvenile Scyliorhinus canicula reared in an Italian public aquarium. Two Vibrio species, V. crassostreae and V. cyclotrophicus, were successfully isolated using different diagnostic methods, while also highlighting the strengths and limitations of these methods.

Summary: Elasmobranchs, as apex predators in the marine food chain, are important bioindicators of environmental pollution. This study examined the helminthic communities, hematological parameters, and trace element concentrations in lesser spotted dogfish from the Tyrrhenian Sea. The findings suggest correlations between these factors and environmental pollution.

Summary: Metals (trace elements and rare earth elements, REEs) were analysed in different organs of ex situ spotted dogfish (Scyliorhinus stellaris) using inductively coupled plasma-mass spectrometry. The study found significant differences in metal concentrations among organs and revealed a close relationship between a balanced diet and animal welfare.

Summary: The growth and reproductive parameters of Scyliorhinus canicula from the south-western Portuguese coast were estimated in this study. The maximum ages for males and females were determined as 12 and 13 years, respectively. The length and age at first maturity were also calculated for both genders.

Summary: The major histocompatibility complex (MHC) is a gene family responsible for pathogen detection and immune response initiation. The MHC is characterized by duplication, natural selection, recombination, and high genetic diversity. This study focused on the MHC II beta diversity in the small-spotted catshark and found three MHC II beta loci with expression in different tissues. The analysis also revealed high sequence diversity, positive selection, recombination, and potential copy number variation in the MHC II beta genes of the small-spotted catshark.

Summary: The small-spotted catshark, Scyliorhinus canicula, is a valuable model organism for studying morphology and physiology in vertebrate evolution. A detailed staging system is necessary for comparing different studies, especially in investigating the ontogenetic aspects. This study supplements the established system by providing information on the latest pre-hatching stages, which includes significant ontogenetic shifts. The study's framework allows for comparison of investigations on pre-hatchings of the small-spotted catshark.

Summary: The microbiome in animal's inner body fluids has complex interactions with the environment, and this study found that the microbial profiles vary between blood plasma and seminal plasma in small-spotted catsharks. The microbiome in blood plasma is not affected by the habitat, while in seminal plasma, microbial diversity differs between aquarium and wild animals. Proteobacteria are the dominant bacteria in both inner body fluids and habitats, and only a few genera are shared between different habitats.

Summary: This study analyzed stable isotopes (δ13C and δ15N) in the vertebrae of Scyliorhinus canicula to investigate potential trophic shifts in relation to sex and maturity condition. The results showed significant differences in δ13C and δ15N values between immature and mature individuals. The peripheral vertebrae, corresponding to the mature state, had higher δ15N values and lower δ13C values compared to the central vertebrae related to the immature state.

Summary: This study investigates the physiological responses of catsharks to air exposure and identifies specific enzymes involved in amino acid catabolism and ammonium excretion. The study demonstrates that catsharks rely on white muscle amino acid catabolism to meet the energy demand during stress and utilize a Na+/H+ exchanger enzyme for ammonium excretion. Understanding the relationship between acute stress and osmoregulation in elasmobranchs is important for studying these ancient vertebrates.

Summary: The study compared the male reproductive function of wild-captured and aquarium-housed small-spotted catsharks, demonstrating good in vitro semen quality in aquarium-housed sharks. Wild-caught sharks showed better semen volume and total sperm number, while aquarium-housed sharks had higher total sperm motility.

Summary: This study analyzed the proteomes of different stages of spermatogenesis in Scyliorhinus canicula and identified proteins related to RNA processing, chromosome-related processes, cilium organization, and cilium activity. Proteins involved in cellular stress, ubiquitin-dependent degradation, post-transcriptional regulation, and regulation of cellular homeostasis were also found. Additionally, the study highlighted the potential roles of some proteins in spermatogenesis that need further exploration and emphasized the evolutionary context of spermatogenesis regulation.

Summary: Neurotrophins play a crucial role in the differentiation, survival, neurite outgrowth, and plasticity of neurons. Abnormal neurotrophin-signaling is associated with neuropathies, neurodegenerative disorders, and age-related cognitive decline. BDNF is the most highly expressed neurotrophin in the brain, particularly in the hippocampus and cerebral cortex.

Summary: Rook et al. established a viral gene transfer system for optogenetics in pigeons, showing that AAV1 is the most efficient vector for ChR2 expression in various brain regions. They also demonstrated the involvement of the entopallium in contrast perception through transient optical stimulation of ChR2 expressing cells. This study verifies the feasibility of optogenetics in avian species and paves the way for other methods relying on viral gene transfer in birds.

Summary: It is found that there is strong polarization sensitivity in GPCR-based neurotransmitter sensors, which leads to the loss of membrane signal in dendrites parallel to the polarization direction of the excitation beam. By designing an optical device that generates interleaved pulse trains of orthogonal polarization, the directional bias in fluorescence and second-harmonic (SHG) images can be eliminated.

Summary: Understanding how neuronal networks generate complex behavior is a major goal in Neuroscience. Neurotransmitter and neuromodulators play crucial roles in information flow between neurons, and visualizing their dynamics is essential for understanding brain function. In recent years, single-wavelength biosensors based on PBPs or GPCR have been developed to detect neurotransmitter release with high resolution. This review discusses the progress, limitations, and future directions of these sensors.
