Taste Receptors and Sperm Biology
Taste receptors were first described as sensory receptors located on the tongue, where they are expressed in small clusters of specialized epithelial cells. Taste receptors and components of the coupled taste transduction cascade are also expressed during the different phases of spermatogenesis as well as in mature spermatozoa from mouse to humans and the overlap between the ligand spectrum of taste receptors with compounds in the male and female reproductive organs makes it reasonable to assume that sperm “taste” these different cues in their natural microenvironments.

Autophagy in Parenchymal and Non-Parenchymal Liver Cells
Autophagy is a highly conserved intracellular process for the ordered degradation and recycling of cellular components in lysosomes. In the liver this process is relevant for maintaining liver homeostasis, especially in conditions of hepatic insults.

Spatiotemporal Distribution of VPS13A in the Mouse Brain
Loss-of-function mutations in the human vacuolar protein sorting 13 homolog A (VPS13A) gene cause Chorea-acanthocytosis (ChAc). As very little is known about the VPS13A expression in the brain, The main objective of this work was to assess for the first time the spatiotemporal distribution of VPS13A in the mouse brain. Understanding the distinct expression pattern of VPS13A provides relevant information to unravel pathophysiological hallmarks of ChAc.

Blood-Spinal Cord Barrier
The blood-spinal cord barrier (BSCB) has been long thought of as a functional equivalent to the blood-brain barrier (BBB), restricting blood flow into the spinal cord. The spinal cord is supported by various disc tissues that provide agility and has different local immune responses compared to the brain. Though physiologically, structural components of the BSCB and BBB share many similarities, the clinical landscape significantly differs.

One-Carbon Metabolism Modulates Ageing and Neurodegeneration
One-carbon metabolism (OCM) is a network of biochemical reactions delivering one-carbon units to various biosynthetic pathways. The folate cycle and methionine cycle are the two key modules of this network that regulate purine and thymidine synthesis, amino acid homeostasis, and epigenetic mechanisms. Intersection with the transsulfuration pathway supports glutathione production and regulation of the cellular redox state. Dietary intake of micronutrients, such as folates and amino acids, directly contributes to OCM, thereby adapting the cellular metabolic state to environmental inputs. The contribution of OCM to cellular proliferation during development and in adult proliferative tissues is well established. Nevertheless, accumulating evidence reveals the pivotal role of OCM in cellular homeostasis of non-proliferative tissues and in coordination of signaling cascades that regulate energy homeostasis and longevity.

Impaired Mitophagy in Neurons and Glial Cells
Aging is associated with a decline in cognitive function, which can partly be explained by the accumulation of damage to the brain cells over time. Neurons and glia undergo morphological and ultrastructure changes during aging. Over the past several years, it has become evident that at the cellular level, various hallmarks of an aging brain are closely related to mitophagy. The importance of mitochondria quality and quantity control through mitophagy is highlighted by the contribution that defects in mitochondria–autophagy crosstalk make to aging and age-related diseases.

Genetics and Transcriptomics of Melanoma Metastasis
Melanoma is a deadly skin cancer with rapidly increasing incidence worldwide. The progression from melanomagenesis to metastasis is known to differ between the various subtypes of melanoma, which are defined by their disparate clinical, histopathologic, and genetic features.

Isolation and Purification of EVs
Extracellular vesicles are sacs that are secreted by almost all types of cells and are responsible for intracellular communication. They inherit their content and characteristics from their donor cells. Pathological and physiological characteristics of donor cells are reflected in the appearance of specific nucleotide and proteins (on the EV surface or in their content).

Hippo Pathway in Glioblastoma
Glioblastoma (GBM) represents the most common and malignant tumor of the Central Nervous System (CNS), affecting both children and adults. GBM is one of the deadliest tumor types and it shows a strong multidrug resistance (MDR) and an immunosuppressive microenvironment which remain a great challenge to therapy.

SHED-Dependent Oncogenic Signaling of the PEAK3 Pseudo-Kinase
The human kinome is composed of about 50 pseudo-kinases with unclear function, because they are predicted to be catalytically inactive; however, they are shown to play an important role in cancer, similar to active kinases. Understanding how these pseudo-kinases promote tumor formation despite their catalytic inactivity is a great challenge, which may lead to innovative anti-cancer therapies. The PEAK1 and 2 pseudo-kinases have emerged as important components of the protein tyrosine kinase pathway implicated in cancer progression. They can signal using a scaffolding mechanism via a conserved split helical dimerization (SHED) module.
