Programmed cell death (PCD; sometimes referred to as cellular suicide ) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle. For example, the differentiation of fingers … Visa mer The concept of "programmed cell-death" was used by Lockshin & Williams in 1964 in relation to insect tissue development, around eight years before "apoptosis" was coined. The term PCD has, however, been a source of … Visa mer An atrophic factor is a force that causes a cell to die. Only natural forces on the cell are considered to be atrophic factors, whereas, for example, agents of mechanical or … Visa mer Programmed cell death in plants has a number of molecular similarities to animal apoptosis, but it also has differences, the most obvious being the presence of a cell wall and the lack of an immune system that removes the pieces of the dead cell. Instead of an … Visa mer The occurrence of programmed cell death in protists is possible, but it remains controversial. Some categorize death in those organisms as unregulated apoptosis-like cell death. Biologists had long suspected that mitochondria originated … Visa mer • Apoptosis or Type I cell-death. • Autophagic or Type II cell-death. (Cytoplasmic: characterized by the formation of large Visa mer The initial expansion of the developing nervous system is counterbalanced by the removal of neurons and their processes. During the development of the nervous system almost 50% of developing neurons are naturally removed by programmed cell death (PCD). PCD in … Visa mer The social slime mold Dictyostelium discoideum has the peculiarity of either adopting a predatory amoeba-like behavior in its unicellular form or coalescing into a mobile slug-like form when dispersing the spores that will give birth to the next generation Visa mer WebbThe terms senescence and programmed cell death (PCD) have led to some confusion. Senescence as visibly observed in, for example, leaf yellowing and petal wilting, has often been taken to be synonymous with the programmed death of the constituent cells. PCD also obviously refers to cells, which show …
