Why are some cells not able to always kill themselves using apoptosis and instead have to rely on a white blood cell? How do cells use energy? Why is a red blood cell considered a cell? Why do cells contain a small amount of ATP?
Rather than leaving a cell that is fundamentally prevented from undergoing apoptosis, very often the resulting cancer cell is quite ready to undergo apoptosis compared to normal cells. This distinction is, indeed, an important determinant of the therapeutic index for conventional chemotherapy that we ...
Why does a cell undergo mitosis? Why don't red blood cells have MHC1? When stained with Wright's stain basophil cells do what? Why it is beneficial for cells to be small? Why do B-cells need helper T-cells? Why are animal cells more irregularly shaped than plant cells?
Hence, without the benefit of elevated Bcl-2, these activated, HIV-infected T-cells should preferentially undergo apoptosis. At the same time, lowering the Bcl-2 levels in bystander T-cells makes them less susceptible to external death signals. Thus, suppression of Bcl-2 should concurrently ...
However, when resting B cells are activated in vitro, generally only CSR can be observed (Stavnezer, 2011; A. Durandy, unpublished), but the VH region does not undergo SHM. In the in vitro activated B cells, SHM mutations do occur in the switch regions activated by the respective ...

The fragile X mental retardation protein developmentally regulates ...
the possibility exists that OECs may phagocytose not only pathogens but also infected cells (both OECs and other cell types) before the cells can undergo neoplastic transformation as a result of infection. Cells infected with certain viruses, for example, change their expression of “eat me” si...
What cells undergo meiosis? Does meiosis produce haploid or diploid cells? Which process is involved in cell and tissue repair? a. apoptosis b. meiosis c. endocytosis d. mitosis Which was the first cell or cell-type to achieve mitosis (cell division)? Ho...
Why do animals with millions of cells need a circulatory system while animals with only a few cells can do without one?Circulatory System:The circulatory system is the body system that is responsible for transporting nutrients and blood throughout the en...
Many proteins that undergo transport through the secretory pathway have signal peptides of 15–35 aa. length located predominantly at their N-termini. They are often cleaved by various proteases during their subcellular transport. This results in the matu...
