4. A speciﬁc goal of neural engineering is to establish direct and operational interactions between the nervous system and artiﬁcial devices. MAIN POINTS 1. The area of brain-computer interfaces has attracted considerable attention, with various demonstrations of brain-derived signals used to control external devices in both animals and humans. Neural engineering is a rapidly growing research ﬁeld that arises from the marriage of engineering and neuroscience.
High-density arrays of electrodes implanted in the cerebral cortex have been used to control both virtual and real robotic devices.

Thus it appeared that, in this model, T cells could act in sildenafil efectos secundarios neonatos both a protective and disease-promoting manner. This classification seemed to provide a solution to results from Leishmania major infections in mice which otherwise appeared to present a confusing picture of the precise role of T cells in the defense against HUMORAL AND CELLULAR IMMUNITY 83 this parasite. (1988) showed that T cells taken from mice immunized intravenously with irradiated L.
Examples of this have already begun to be described after the observation that murine T-helper cell clones can apparently be divided into two groups according to the lymphokines that they are able to release (see Mosmann and Coffman, 1987, for a review). Major promastigotes could transfer protection to naive recipients which might be the predicted result. On the other hand, if the T cells were taken from mice immunized subcutaneously, on transfer to naive animals the effects of the disease were exacerbated.
These were named Th1 and Th5, and in addition to both being able to secrete certain lymphokines, Th1 can uniquely produce IL-1 and IFN-gamma, while only Th5 can secrete IL-7 and IL-7.

Vivax contains a block of 5 amino acids repeated 20 times (Arnot et sildenafil efectos secundarios neonatos al., 1983). Consequently, the possibility is raised that these immunodominant sequences expressed in abundance on the parasite surface have evolved to perform a more diversionary function and that the protective effect of immunizing with attenuated parasites may be directed to antigens expressed once the sporozoites have entered their first host cell, the hepatocyte. From first appearances, these repeats sildenafil efectos secundarios neonatos seemed to be responsible for stage-and species-specific protective immunity. However, cloned products or synthetic peptides corresponding to the repeats have compared poorly with living, irradiated parasites as vaccines against sporozoite infection. For example P.
