Life and death by death receptors

Apoptosis signaling by death receptors.

Death receptors have been recently identified as a subgroup of the TNF-receptor superfamily with a predominant function in induction of apoptosis. The receptors are characterized by an intracellular region, called the death domain, which is required for the transmission of the cytotoxic signal. Currently, five different such death receptors are known including tumor necrosis factor (TNF) recept...

Neurotransmitter receptors in the life and death of oligodendrocytes

Oligodendrocytes are crucial to the function of the mammalian brain: they increase the action potential conduction speed for a given axon diameter and thus facilitate the rapid flow of information between different brain areas. The proliferation and differentiation of developing oligodendrocytes, and their myelination of axons, are partly controlled by neurotransmitters. In addition, in models ...

Life & Death

life insurance policy (college freshman), about the same as the Gettysburg Address, and much less readable than Hemingway (fifth grade level). I used more words per sentence than Hemingway (18.5 versus 13.5) but less than Lincoln (26.8). I used longer words than any of the references (4.8 letters per word, versus 4.0 for Hemingway) but used fewer prepositions (10.7 percent) than any of the othe...
