Cutting edge: cutting edge commentary: a Copernican revolution? Doubts about the danger theory.
The immune system is often said to function by "self-nonself" discrimination. Recently, some have argued that it actually detects "danger" or "strangers". There are problems with all of these points of view. Given that the immune system has been cobbled together throughout evolution and uses a diverse array of innate and adaptive defense mechanisms, it may not be possible to account for immunit...
متن کاملMicrotubule-severing enzymes at the cutting edge.
ATP-dependent severing of microtubules was first reported in Xenopus laevis egg extracts in 1991. Two years later this observation led to the purification of the first known microtubule-severing enzyme, katanin. Katanin homologs have now been identified throughout the animal kingdom and in plants. Moreover, members of two closely related enzyme subfamilies, spastin and fidgetin, have been found...
متن کاملCutting edge commentary: origins of B-1 cells.
The origin of B-1a cells, a minority population of B cells that express CD5, are abundant in coelomic cavities, and often produce autoantibodies, has been the subject of study for many years. Accumulating evidence demonstrates that the hypothesis that only B cells arising in fetal or neonatal tissues have the potential to become B-1a cells cannot be true. Rather, B cell receptor-mediated signal...
متن کاملCutting-edge Chemistry: Some 19th - Century Russian Contributions. a Commentary
This presentation follows the “classic” paper of Bensaude-Vincent (1) rather closely, but with some additional points and emendations to her argument. One of the first points Kaji makes—that Mendeleev was ambivalent about the status of the atomic theory—can be related to what Bensaude-Vincent delineates as the “strict positivist tradition” to which he belonged. Kaji, however, give this philosop...
متن کاملThe Cutting Edge
“The bigger they are, the harder they fall” is a bit of wisdom that’s been around for a long time. But when it comes to pesticide application, the line should read, “The bigger they are, the closer they fall.” Large droplets are not as likely to drift off-target as smaller droplets. This basic principle lies behind many innovations to reduce drift when spraying herbicides. Nozzle manufacturers ...
