VIRUS-CELL AND CELL-CELL FUSION
Annual Review of Cell and Developmental Biology, 1996▪ Abstract Significant progress has been made in elucidating the mechanisms of viral membrane fusion proteins; both those that function at low, as well as those that function at neutral, pH. For many viral fusion proteins evidence now suggests that a triggered conformational change that exposes a previously cryptic fusion peptide, along with a ...

Cell-to-Cell Heterogeneity in Trypanosomes
Annual Review of Microbiology, 2021Recent developments in single-cell and single-molecule techniques have revealed surprising levels of heterogeneity among isogenic cells. These advances have transformed the study of cell-to-cell heterogeneity into a major area of biomedical research, revealing that it can confer essential advantages, such as priming populations of unicellular organisms

The cell biology of cell-in-cell structures
Nature Reviews Molecular Cell Biology, 2008For decades, authors have described unusual cell structures, referred to as cell-in-cell structures, in which whole cells are found in the cytoplasm of other cells. One well-characterized process that results in the transient appearance of such structures is the engulfment of apoptotic cells by phagocytosis.

Cell-to-cell communication in cultured Sertoli cells
Pfl�gers Archiv European Journal of Physiology, 1985Junctional transfer of ions in monolayer primary cultures of Sertoli cells has been studied by using conventional techniques. Cells were extensively electrically coupled. Membrane voltage displacements caused by the injected current pulses were measured at variable interelectrode distance. Data analyses were based on a thin-sheet model for current flow

CELL INJURY AND CELL DEATH [PDF]
, 2011 WHEN CELLS are damaged, as often occurs during trauma and metabolic stress, the organism has to choose whether to repair the damage by promoting cell survival or remove irreparably injured cells. Cell injury occurs when an adverse stimulus reversibly disrupts the normal, complex homeostatic balance of the cellular metabolism. In this case, after injury

1978
In formulating Cell Theory, Schleiden(1) wrote in 1838: “Every higher organism is an aggregate of fully circumscribed and self-contained unit beings, the cells.” This basic tenet has been extraordinarily fruitful and influential in biology and medicine, and in many aspects its usefulness continues unabated.

Cells interact not only with each other, but also with the extracellular matrix, which consists of proteoglycan, collagen, elastin, and multiadhesive proteins such as laminin. Both cell/cell and cell/matrix interactions require cell adhesion molecules, some of which occur in cell junctions.

Trends in Biochemical Sciences, 1976
Abstract Several approaches in a variety of biological systems are being used in an attempt to understand cellular recognition at the chemical level. The precise molecular events in cell recognition have not yet been established.

Cell length, cell growth and cell division
Nature, 1976When cells of E. coli reach a certain critical length, which is constant in all growth conditions and eqqal to twice the minimum cell length, they abruptly increase their rate of elongation and divide about 20 min later. Chromosome replication terminates at about this same cell length but is not the signal for the change in rate of cell elongation.

Gene therapy based on the use of viral vectors is entirely dependent on the use of animal cell lines, mainly of mammalian origin, but also of insect origin. As for any biotechnology product for clinical use, viral -vectors have to be produced with cells derived from an extensively characterized cell bank to maintain the appropriate standard for ...
