In general, chemotherapy medications work by attacking cells or by preventing them from growing and dividing. Cancer cells tend to grow and divide rapidly and uncontrollably, and many chemotherapy ...

Stem cells are cells that have the capacity to self-renew by dividing and to develop into more mature, specialised cells. Stem cells can be unipotent, multipotent, pluripotent or totipotent ...

Newly discovered brain cells count each bite before sending the order to cease eating a meal. Columbia scientists have found specialized neurons in the brains of mice that order the animals to ...

Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart. In this article, we discuss the structure and function of cardiac muscle tissue. We also cover medical ...

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

Neurons are cells in the body that are responsible for transmitting electrical signals through the nervous system. Different types of neurons affect the ability to move, which begins as an impulse, or ...

Transnet Freight Rail (TFR) is now becoming a focused Train Operating Company (TOC) and the rail network is going to be maintained and operated by TRIM. Mesela Nhlapo, CEO of the African Rail ...

Tfc cells share similarities with follicular helper T (Tfh) cells, conventional cytotoxic CD8 + T (Tc cells)cells and follicular regulatory T (Tfr) cells, while they express distinct transcription ...

Follicular T helper cells (Tfh) are a specialized subset of CD4 effector T cells that are crucial for germinal center (GC) reactions and for selecting B cells to undergo affinity maturation. Despite ...

In germinal centers (GCs), T follicular helper cells are supposed to be the positive regulator while T follicular regulatory (Tfr) cells were assigned to be the negative regulators. Indeed, Tfr cells ...
