AI Article Synopsis

  • The text outlines protocols for studying the Golgi structure using thin section transmission electron microscopy (TEM) and DAB cytochemical staining.
  • It highlights methods for chemical fixation and flat embedding to ensure accurate imaging of the Golgi apparatus.
  • The importance of classifying Golgi membranes through software like Microscopy Image Browser for better understanding Golgi morphology is also emphasized.

Article Abstract

Here, we describe protocols for chemical fixation and flat embedding to study the Golgi structure by thin section transmission electron microscopy (TEM) and for 3,3'-diaminobenzidine (DAB) cytochemical staining and pre-embedding immunolabelling to localize specific Golgi proteins. Furthermore, we demonstrate how the Golgi morphology can be elucidated by classifying the Golgi membranes using Microscopy Image Browser-a software that provides anonymization, modelling, and annotation.

Inpp5e Is Critical for Photoreceptor Outer Segment Maintenance.

J Cell Sci

Program in Molecular Medicine, University of Massachusetts Chan Medical School, Suite 213 Biotech II, 373 Plantation Street, Worcester MA 01605, USA.

In humans, inositol polyphosphate-5-phosphatase e (INPP5E) mutations cause retinal degeneration as part of Joubert and MORM syndromes and can also cause non-syndromic blindness. In mice, mutations cause a spectrum of brain, kidney, and other anomalies and prevent the formation of photoreceptor outer segments. To further explore the function of Inpp5e in photoreceptors, we generated conditional and inducible knockouts of mouse Inpp5e where the gene was deleted either during outer segment formation or after outer segments were fully formed.

Chemigenetic Ca2+ indicators report elevated Ca2+ levels in endothelial Weibel-Palade bodies.

Weibel-Palade bodies (WPB) are secretory organelles exclusively found in endothelial cells and among other cargo proteins, contain the hemostatic von-Willebrand factor (VWF). Stimulation of endothelial cells results in exocytosis of WPB and release of their cargo into the vascular lumen, where VWF unfurls into long strings of up to 1000 µm and recruits platelets to sites of vascular injury, thereby mediating a crucial step in the hemostatic response. The function of VWF is strongly correlated to its structure; in order to fulfill its task in the vascular lumen, VWF has to undergo a complex packing/processing after translation into the ER.

Introduction: Cytomegalovirus (CMV) infection reorganizes early endosomes (EE), recycling endosome (RE), and trans-Golgi network (TGN) and expands their intermediates into a large perinuclear structure that forms the inner part of the cytoplasmic assembly complex (AC). The reorganization begins and results with the basic configuration (known as pre-AC) in the early (E) phase of infection, but the sequence of developmental steps is not yet well understood. One of the first signs of the establishment of the inner pre-AC, which can be observed by immunofluorescence, is the accumulation of Rab10.

The ultrastructural organization of the nuclei of the tegmental region in juvenile chum salmon () was examined using transmission electron microscopy (TEM). The dorsal tegmental nuclei (DTN), the nucleus of (NFLM), and the nucleus of the oculomotor nerve (NIII) were studied. The ultrastructural examination provided detailed ultrastructural characteristics of neurons forming the tegmental nuclei and showed neuro-glial relationships in them.

The brain presents various structural and functional sex differences, for which multiple factors are attributed: genetic, epigenetic, metabolic, and hormonal. While biological sex is determined by both sex chromosomes and sex hormones, little is known about how these two factors interact to establish this dimorphism. Sex differences in the brain also affect its resident immune cells, microglia, which actively survey the brain parenchyma and interact with sex hormones throughout life.
