    Upon endocytosis by an antigen-presenting cell (APC), the antigen (Ag) may be altered by the acidic conditions within the endosome or by proteolytic how long does viagra remain in your system activity within the lysosome. Presumably, those antigens which have a low affinity for MHC molecules will be completely degraded by the cell, e.g. Those antigens which have a strong affinity will interact and will be able to participate in the presentation how long does viagra remain in your system process to T cells at the membrane surface. This ‘processed’ antigen (Ag*) then will or will not possess an affinity for MHC Class II molecules (Ia).

    The aversive stimulus effects of opioid withdrawal that form the basis for the motivational effects of opioid withdrawal and conditioned withdrawal can how long does viagra remain in your system be measured readily using place aversion, and such place aversions last up to 15 weeks (Stinus et al., 1989, 1998). This extra time appears to be randomly spent in either the vehicle-paired or neutral compartment, as time spent in the naloxone-paired compartment declines as a function of naloxone dose. [Reproduced with permission from Azar et al., 2001.] NEUROBIOLOGICAL MECHANISM—NEUROCIRCUITRY 185 Studies of the neurobiological substrates of physical dependence on opioids have revealed multiple sites of action, including the periaqueductal gray , dorsal thalamus , and locus coeruleus. The sites in the brain responsible how long does viagra remain in your system for more motivational or emotional changes associated with opioid withdrawal have been localized to structures in the basal forebrain, however. Injection of hydrophilic opioid antagonists into certain sites such as the nucleus accumbens and the amygdala were largely negative for eliciting physical signs of opioid withdrawal but produced motivational signs of withdrawal as measured by both a suppression of operant responding in dependent rats and the establishment of conditioned place aversions , in support of this hypothesis.

    Except where noted, all morphine/naloxone treatment conditions represent two conditioning cycles.
