Recycling of endocytic BDNF through extracellular vesicles in astrocytes.
Sci Rep

Neurovascular Unit Research Group, Korea Brain Research Institute (KBRI), Daegu, South Korea.
Brain-derived neurotrophic factor (BDNF) plays an essential role in regulating diverse neuronal functions in an activity-dependent manner. Although BDNF is synthesized primarily in neurons, astrocytes can also supply BDNF through various routes, including the recycling of neuron-derived BDNF. Despite accumulating evidence for astrocytic BDNF uptake and resecretion of neuronal BDNF, the detailed mechanisms underlying astrocytic BDNF recycling remain unclear.

This paper presents a review of the potential role of the endoplasmic reticulum/Golgi complex and intracellular vesicles in mediating events leading to or associated with vertebrate tissue mineralization. The possible importance of these organelles in this process is suggested by observations that calcium ions accumulate in the tubules and lacunae of the endoplasmic reticulum and Golgi. Similar levels of calcium ions (approaching millimolar) are present in vesicles derived from endosomes, lysosomes and autophagosomes.

is a significant agricultural pest primarily affecting Solanaceae plants, resulting in substantial economic losses in agriculture. Insect saliva is an intermediary between insects and plants, playing a crucial role in modulating host adaptability and plant defense. This study analyzed the adaptive differences of on four plants using the two-sex life table method.

J Adv Res
January 2025
Introduction: Cyclin-Dependent Kinase 8 (CDK8), a CDK family member, regulates the development of inflammatory processes through transcriptional activation. The involvement of CDK8 in osteoarthritis (OA) progression is not yet understood.
Objectives: This study aims to investigate whether CDK8, through its transcriptional regulatory functions, collaborates with NF-κB in chondrocytes to regulate the transcription of senescence-associated secretory phenotype (SASP) genes, thereby exacerbating the inflammatory microenvironment in the progression of osteoarthritis (OA), and to explore the specific mechanisms involved.
Bone Marrow Adipocytes as Novel Regulators of Metabolic Homeostasis: Clinical Consequences of Bone Marrow Adiposity.

Purpose Of Review: Bone marrow adipose tissue is a distinctive fat depot located within the skeleton, with the potential to influence both local and systemic metabolic processes. Although significant strides have been made in understanding bone marrow adipose tissue over the past decade, many questions remain regarding their precise lineage and functional roles.
Recent Findings: Recent studies have highlighted bone marrow adipose tissue's involvement in continuous cross-talk with other organs and systems, exerting both endocrine and paracrine functions that play a crucial role in metabolic homeostasis, skeletal remodeling, hematopoiesis, and the progression of bone metastases.
