It is common experience that we can talk, although with difficulty, with someone even if there is a louder noisy crowd around, because we can "lock on" to the speaker. In other words, we can make a conversation even if the background noise is higher than the "signal". To be ...
Several proto-oncogene–derived proteins form a part of cell surface receptors for GFs. The binding of GF ligand to receptor is the initial stage of the delivery of mitogenic signals to cells. Their role in carcinogenesis may be through structural alterations in these proteins, leading to enhanced...
The interaction of T cells with EC or thymic epithelium constitutes a unique requirement for the expression of TdT; mitogens or alloantigens fail to do so (Rubenfeld et al., 1981). In our hands, autologous EC revealed stimulatory properties for T cells at least as high as allogeneic EC ...
