Immunolocalization of an enterotoxic glycoprotein exoantigen on the secretory organelles of Cryptosporidium parvum sporozoites

Parasite, 2004
In this study, the fine ultrastructures of the secretory organelles of C. parvum sporozoites were demonstrated using transmission electron microscopy (TEM).

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, EarlyView.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Immunolocalization of Hsp60 in Legionella pneumophila [PDF]

Journal of Bacteriology, 1998
ABSTRACT One of the most abundant proteins synthesized by Legionella pneumophila , particularly during growth in a variety of eukaryotic host cells, is Hsp60, a member of the GroEL family of molecular chaperones. The present study was initiated in response to a growing number of reports suggesting that for

Anemia‐associated mutations disrupt the CDIN1‐Codanin1 complex in inherited congenital dyserythropoietic anemia I (CDA‐I) disease

The FEBS Journal, EarlyView.
Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...

Arabinogalactan Proteins Mark the Generative Cell–Vegetative Cell Interface in Monocotyledonous Pollen Grains

Cells
Arabinogalactan proteins (AGPs: hydroxyproline-rich glycoproteins) are ubiquitous in plants and play various functions in cases of development and reproduction.

Immunohistochemical localization of Kisspeptin and its receptor in the placentome of buffalo (Bubalus bubalis)

Indian Journal of Animal Sciences, 2022
Evidence for extra-hypothalamic expression of kisspeptinergic system is emerging. The present study documents the imuunolocalization of the kisspeptin and its receptor in the placentome of buffalo.

Branchial localization of acid (A‐type) and base (B‐type) excreting ionocytes in Amazonian stenohaline freshwater Potamotrygon ray

Journal of Fish Biology, EarlyView.
Abstract The branchial epithelium of Potamotrygon—a member of the only strictly freshwater elasmobranch family Potamotrygonidae—was observed via immunohistochemistry, and two distinct forms of ionocytes were identified. The acid (A‐type) and base (B‐type) secreting cells with respective basolateral–apical localizations of Na+/K+‐ATPase–Na+/H+ exchanger

Occludin immunolocalization and protein expression in goldfish [PDF]

Journal of Experimental Biology, 2008
SUMMARYTight junctions (TJs) are an integral component of models illustrating ion transport mechanisms across fish epithelia; however, little is known about TJ proteins in fishes. Using immunohistochemical methods and Western blot analysis, we examined the localization and expression of occludin, a transmembrane TJ protein, in goldfish tissues.

Collagen and microvascular alterations contribute to neuromuscular degeneration and disease progression in chronic intestinal pseudo‐obstruction

Journal of Internal Medicine, EarlyView.
Abstract Background Chronic intestinal pseudo‐obstruction (CIPO) is a severe gastrointestinal motility disorder that may be idiopathic or associated with systemic disease. In idiopathic cases, the pathophysiological mechanisms remain poorly defined. Although mutations in angiogenic factors have been reported in mitochondrial forms of CIPO, their role ...
