Hormones coordinate different body functions by carrying messages through the bloodstream to target cells and tissues. Hormonal imbalances occur through inadequate or excess hormone synthesis, which ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...

B lymphocytes exhibit dual roles in tumorigenesis, acting as both allies and adversaries in the tumor microenvironment (TME). Their anti-tumor functions include recognizing tumor-associated antigens, ...

The human immune system is like an army of specialized soldiers (immune cells) each with a unique role to play in fighting disease. In a new study published in Nature, led by scientists at the Allen ...

St. Jude Children's Research Hospital scientists have discovered how tumors disable immune "gatekeeper" cells that alert the rest of the immune system to the presence of cancer - and how restoring ...

A new study from The Hospital for Sick Children (SickKids) and Institut Curie reveals how stem cells sense and respond to their environment, with implications for inflammatory bowel disease and ...

All cells need to sense and respond to their environment—to know when to activate genes, build proteins and carry out their basic functions. One of the most well-studied cellular responses is how they ...

The death of an organism does not spell the end for its cells, according to new research. Cells have been shown to continue to function even after the organism they originated from is deceased, often ...
