...things may be looking up, thanks to advances in molecular immunology that have spurred the creation of new generation of drugs. It is becoming clear that a cell called CD4+, or helper T cell, is a central player in both the healthy and the pathological immune response. "The activation of the T cell-like the branches of government-is controlled by a series of checks and balances," explains Dr. C. Garrison Fathman, a clinical immunologist at Stanford University...
...those checks is the T cell’s dependence on another cellular player: the antigen presenting cell. The APC is an omnivorous creature whose job, among other things, is to gobble up microbial invaders. To initiate the immune response, the APC coughs up a molecule from the bug it has eaten, latches onto a helper T cell and "presents" it with the target molecule, instructing the T cell to prepare its troops for war. This activation is tightly controlled. It cannot occur without the lock-step interaction of a several proteins on the surface of both cells-one of which...
While Gore aides arranged clearances with the security folks at the guardhouse, Bon Jovi worked his cell phone, and a short while later appeared none other than Tom Petty, John Popper of Blues Traveler, and a raft of studio musicians. About 45 minutes later, Stevie Wonder showed up for a couple of numbers, one of which was "Higher Ground...
Gusmorino and Lee propose an ambitious agenda of student services for the next year, and the pair's record on the council make us believe they can make good on their promises. Central to their platform is a discounted Harvard cell phone plan, parties until 2 a.m., a CUE Guide to concentrations, an impartial advocate to the Ad Board for victims of sexual assault, and a first-year rape prevention program. Historically, candidates for the council's highest positions have promised more than they can deliver; if anything, Gusmorino and Lee have thus far exceeded expectations. The council will have...
...MITNICK is forbidden by the terms of his prison release to use a computer or the Internet. But those hackers are a wily sort. Using his father as an agent, Mitnick has been conducting an online celebrity auction (if you consider a techno-felon a celebrity), selling off his cell phone for $355 and getting $510 for his TRS-80 computer. Geek love ran wild when Mitnick's prison ID card went up for sale; that's when eBay decided there might be some legal issues here. After the site stopped the auction and Yahoo and Amazon also refused...
