Imaging plant embryos at the cellular level over time is technically challenging, since the embryo, once its protective seed coat is removed, must be kept viable and unstressed on a microscope slide for the duration of the experiment. Here we describe a procedure and suitable apparatus for the visualization, over several days, of changes in endoplasmic reticulum (ER) morphology associated with the process of germination in Arabidopsis thaliana seeds. Moreover, we also present a user-friendly image analysis tool, which enables subtle perturbations in the ER network to be measured.

Objectives: Endoplasmic reticulum (ER) stress-induced protein homeostasis perturbation is a core pathological element in the pathogenesis of neurodegenerative diseases. This study aims to clarify the unique role played by C/EBP homologous protein (CHOP) as a biomarker of the unfolded protein response (UPR) in the etiology of chronic pain and related cognitive impairments following chronic constrictive nerve injury (CCI).
Methods: The memory capability following CCI was assessed utilizing the Morris water maze (MWM) and fear conditioning test (FCT).

Introduction: The cardiotoxicity and subsequent Heart Failure (HF) induced by Doxorubicin (DOX) limit the clinical application of DOX. Valsartan (Val) is an angiotensin II receptor blocker that could attenuate the HF induced by DOX. However, the underlying mechanism of Val in this process is not fully understood.

Tumor-specific T cells play a vital role in potent antitumor immunity. However, their efficacy is severely affected by the spatiotemporal orchestration of antigen-presentation as well as the innate immune response in dendritic cells (DCs). Herein, we develop a minimalist nanovaccine that exploits a dual immunofunctional polymeric nanoplatform (DIPNP) to encapsulate ovalbumin (OVA) via electrostatic interaction when the nanocarrier serves as both STING agonist and immune adjuvant in DCs.

Objective: Neuronal damage is criminal to cognitive dysfunction, closely related to endoplasmic reticulum stress (ERS). However, due to the pathogenesis of endotoxin-induced long-term cognitive dysfunction is not fully clarified, there is still a lack of effective treatment. This study was conducted to explore the protective effects and mechanism of rosmarinic acid (RA) against ERS in endotoxin-induced cognitive dysfunction in mice and neuronal injury in cells.

Epilepsy is one of the most common neurological disorders. Calcium dysregulation and neuroinflammation are essential and common mechanisms in epileptogenesis. Sarco/endoplasmic reticulum (ER) Ca-ATPase 2b (SERCA2b), a crucial calcium regulatory pump, plays pathological roles in various calcium dysregulation-related diseases.
