Cell Propagation of Cholera Toxin CTA ADP-Ribosylating Factor by Exosome Mediated Transfer [PDF]
In this study, we report how the cholera toxin (CT) A subunit (CTA), the enzyme moiety responsible for signaling alteration in host cells, enters the exosomal pathway, secretes extracellularly, transmits itself to a cell population.

Entry pathways of herpes simplex virus type 1 into human keratinocytes are dynamin- and cholesterol-dependent [PDF]
Herpes simplex virus type 1 (HSV-1) can enter cells via endocytic pathways or direct fusion at the plasma membrane depending on the cell line and receptor(s).

An investigation into the relationship between small intestinal fluid secretion and systemic arterial blood pressure in the anesthetized rat [PDF]
In the absence of an ability to absorb fluid by cellular uptake mechanisms, fluid movement in vivo from the perfused rat intestine is absorptive when the diastolic blood pressure is normal or very low but is secretory when blood pressure falls below ...

The Roles of Membrane Rafts in CD32A-Mediated Phagocytosis [PDF]
Membrane rafts are highly dynamic heterogeneous sterol- and sphingolipid-rich micro-domains on cell surfaces. They are generally believed to provide residency for cell surface molecules (e.g., adhesion and signaling molecules) and scaffolding to ...

Retrograde transport pathways utilised by viruses and protein toxins [PDF]
A model has been presented for retrograde transport of certain toxins and viruses from the cell surface to the ER that suggests an obligatory interaction with a glycolipid receptor at the cell surface. Here we review studies on the ER trafficking cholera

Microcavity supported lipid membranes: versatile platforms for building asymmetric lipid bilayers and for protein recognition [PDF]
Microcavity supported lipid bilayers (MSLB) are contact-free membranes suspended across aqueousfilled pores that maintain the lipid bilayer in a highly fluidic state and free from frictional interactions with substrate.

Subunit Structure of Cholera Toxin [PDF]
SUMMARY Two types of subunit, with molecular weights estimated to be 28000 and 8000, were demonstrated in the cholera exo-enterotoxin by sodium dodecylsulphate polyacrylamide electrophoresis. The light (L) component but not the heavy (H) was demonstrable in the antigenically identical natural toxoid.

Comparative Study of Xenobiotic-Free Media for the Cultivation of Human Limbal Epithelial Stem/Progenitor Cells. [PDF]
The culture of human limbal epithelial stem/progenitor cells (LSCs) in the presence of animal components poses the risk of cross-species contamination in clinical applications.

Binding of NAD+ by cholera toxin [PDF]
1. The Km for NAD+ of cholera toxin working as an NAD+ glycohydrolase is 4 mM, and this is increased to about 50 mM in the presence of low-Mr ADP-ribose acceptors. Only molecules having both the adenine and nicotinamide moieties of NAD+ with minor alterations in the nicotinamide ring can be competitive inhibitors of this reaction. 2.
