Dual localization of receptor-type adenylate cyclases and cAMP response protein 3 unveils the presence of two putative signaling microdomains in Trypanosoma cruzi

open access: yesmBio, 2023
Trypanosoma cruzi is the etiologic agent of Chagas disease, a leading cause of disability and premature death in the Americas. This parasite spends its life between a triatomine insect and a mammalian host, transitioning between developmental stages in ...

A novel mechanosensitive channel controls osmoregulation, differentiation, and infectivity in Trypanosoma cruzi

open access: yeseLife, 2021
The causative agent of Chagas disease undergoes drastic morphological and biochemical modifications as it passes between hosts and transitions from extracellular to intracellular stages.

THE ACTIVITY OF THE CONTRACTILE VACUOLE IN A SUCTORIAN (TOKOPHRYA INFUSIONUM)

open access: greenThe Biological Bulletin, 1951
1. Evidence is presented for the existence of a close relation between the behavior of the contractile vacuole and several phases of the functional activity of Tokophrya infusionum.2. When the process of feeding starts the pulsation rate of the contractile vacuole rises suddenly, remains high during feeding and falls gradually on cessation of the ...

Copine A regulates the size and exocytosis of contractile vacuoles and postlysosomes in Dictyostelium

open access: yesFEBS Open Bio, 2020
Copines are a family of cytosolic proteins that associate with membranes in a calcium‐dependent manner and are found in many eukaryotic organisms. Dictyostelium discoideum has six copine genes (cpnA‐cpnF), and cells lacking cpnA(cpnA−) have defects in ...

The Nature of the Contractile Vacuole [PDF]

open access: yesNature, 1925
FOR some years we have been investigating the cytoplasmic bodies in the protozoa. In NATURE of March 10, 1923, we were able to give the first account of the stages undergone by the Golgi bodies in the sporozoon Adelea. A full account of this work has been published in the Q.J.M.S., vol. 67, Part III., 1923. More recently M. Ph.

Quantitative conversion of biomass in giant DNA virus infection

open access: yesScientific Reports, 2021
Bioconversion of organic materials is the foundation of many applications in chemical engineering, microbiology and biochemistry. Herein, we introduce a new methodology to quantitatively determine conversion of biomass in viral infections while ...

Structural organization of Trypanosoma cruzi

open access: yesMemorias do Instituto Oswaldo Cruz, 2009
Since the initial description of Trypanosoma cruzi by Carlos Chagas in 1909, several research groups have used different microscopic techniques to obtain detailed information about the various developmental stages found in the life cycle of this ...

Myofiber structure, sarcoplasmic reticulum Ca<sup>2+</sup> handling, and contractile function after muscle-damaging exercise in humans. [PDF]

open access: yesPhysiol Rep
Alterations in myofiber Ca2+ handling systems after eccentrically, damaging exercise. Created in https://BioRender.com. Abstract Exercise‐induced muscle damage (EIMD) is characterized by a severe and prolonged decline in force‐generating capacity. However, the precise cellular mechanisms underlying the observed long‐lasting decline in force‐generating ...

Evolutionarily conserved sites in yeast tropomyosin function in cell polarity, transport and contractile ring formation

open access: yesBiology Open, 2015
Tropomyosin is a coiled-coil protein that binds and regulates actin filaments. The tropomyosin gene in Schizosaccharomyces pombe, cdc8, is required for formation of actin cables, contractile rings, and polar localization of actin patches.
