Several accessory molecules were shown to play important roles in T cell functions and be in close proximity to the T cell receptor (TcR/CD3). The L-selectin molecule (Leu8, LAM1-1, LECAM1) also plays an important role in lymphocyte homing and proliferation. We were interested in determining the proximity of this molecule to the TcR/CD3 complex on live peripheral human T cells. Using a fluoresc...

Players may be allowed to both buy and sell the same commodity in a strategic market game. Any outcome of such a game can also be obtained as an outcome of a game in which players either buy or sell.

This effect is most prominent in periods of high market sentiment (e.g., the 1997-2001 period) and is stronger for glamour firms. This effect does not arise from sell recommendations being a proxy for low...
