New infections cause dormant viruses to reactivate

The famous slogan is "A diamond is forever," but that phrase might be better suited to herpes: Unlike most viruses, which succumb to the immune system's attack, herpes remains in the body forever, lying in wait, sometimes ...

RNA processing and antiviral immunity

The RIG-I like receptors (RLRs) are intracellular enzyme sentries that detect viral infection and initiate a first line of antiviral defense. The cellular molecules that activate RLRs in vivo are not clear.

A sarcoma (from the Greek sarx (σάρκα) meaning "flesh") is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancerous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma. Sarcomas are quite rare - common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.
