Web11 apr. 2024 · During the cell cycle, bacterial cells double their mass, replicate and segregate their chromosome, and synthesize the division septum, which is then split to generate two daughter cells. While several checkpoints are well-studied in the eukaryotic cell cycle, much less is known about the cell cycle regulation in bacteria.

During the development of chimeric antigen receptor (CAR) T-cell therapies almost all clinical trial has shown some adverse events ranging from cytokine mediated toxicities to tissue damage and death. By the present invention, we aim to induce multiple layers of safety checkpoints.

WebThen, the homologous pairs line up at the equator of the cell and are pulled apart. This process is called crossing over, and it is responsible for the genetic variation in the daughter cells. During meiosis II, the sister chromatids are separated and pulled to opposite poles of the cell, in a similar way to the process of mitosis.
