Cell Penetration by Acids
Measurements of the penetration of tissue from Chromodoris zebra are believed to show that a determining factor in penetration involves the establishment of a critical pH (near 3.5) in relation to superficial cell proteins. The rapidity with which this state is produced depends upon acid strength, and upon some property of the acid influencing the speed of absorption; hence it is necessary to c...
متن کاملCell attachment and penetration by influenza virus.
Attachment and penetration of influenza virus into clone 1-5C-4 cells were quantitatively determined by the immunofluorescent cell-counting assay. Aided by centrifugal force, more than 95% of virus inocula of five representative influenza virus strains (A(0)/PR8, A(1)/Ann Arbor, A(2)/Japan, B/Lee, B/Great Lakes) were attached to cells at a linear rate within 10 min, in contrast to approximately...
متن کاملMechanism of Cell Wall Penetration by Viruses
Treatment of radioactively labelled host cells with T1 or T2 bacteriophages induces a leakage of cellular P and S into the medium. Evidence is presented showing that this increased cell permeability is not the result of complete lysis of a small fraction of the cells, but rather is made up of contributions from all or most of the infected population. This leakage of cellular constituents exhibi...
متن کاملThe Kinetics of Penetration
In a model consisting of a non-aqueous layer (representing the protoplasm) placed between an inner, more acid, aqueous layer (representing the sap) and an outer, more alkaline, aqueous solution (representing the external solution bathing a living cell) the penetration of potassium creates an outwardly directed potential against which potassium continues to diffuse inward, thereby increasing the...
متن کاملHost Cell Penetration of Toxoplasma gondii.
The host cell penetration of Toxoplasma gondii was studied with reference to synthesis of a penetration-enhancing factor and the penetrative capacity of the parasites during the various phases of the infectious cycle. HeLa cells as suspension or monolayer cultures were infected with Toxoplasma. After a lag phase shorter than 1 hr, there was a synthesis of penetration-enhancing factor demonstrab...
