    The link of pfizer viagra free receptor internalization to acute tolerance is elaborated by the observation that ligands that produce rapid acute tolerance (e.g., morphine) do not show receptor internalization, whereas ligands that do not show rapid tolerance (e.g., dihydroetorphine) do show acute internalization (Duttaroy and Yoburn, 1996. Narita et al., 1992). Rapid internalization may have a role in functional recovery by promoting receptor ligand dissociation (Yu et al., 1989). Aceto et pfizer viagra free al., 1997).

    Consistent with a differential role for internalization in the efficacy of opioids, promotion of receptor internalization by deleting the β-arrestin-2 gene in mice potentiated and prolonged the analgesic action of morphine, suggesting an impairment of receptor desensitization. Some ligands cause rapid internalization while others such as morphine do not show internalization (Keith et al., 1995), suggesting a role for such intracellular events in the relative efficacy of opioids. Μ and δ receptors, but not κ receptors, also can undergo rapid agonist-mediated internalization via endocytosis (Gaudriault et al., 1993).

    4.33). The increased self-administration FIGURE 8.31 Densities of dopamine D4 recognition sites labeled with 20 nM [2H]sulpiride in the medial and lateral nucleus accumbens (ACBM and ACBL), caudate-putamen (CPU), olfactory tubercle (OTU), substantia nigra pars compacta (SNC), substantia nigra pars reticulata (SNR), and ventral tegmental area (VTA) of alcohol-naive P (n = 7) and NP (n = 8) rats. Rats tested on the elevated plus maze 3–5 weeks postwithdrawal did not show an anxiogenic-like response at baseline, but an anxiogeniclike response was provoked by a mild restraint stress only in the rats with a history of alcohol dependence. Data are the means + SEM.

    Elevations in alcohol intake over baseline and increased stress responsivity persists 5–7 weeks postwithdrawal from chronic alcohol (Roberts et al., 2000a. 2000), valdez et al.. This stress-induced anxiogenic-like response was reversed by a competitive CRF antagonist (Valdez et al., 1999) (Fig.

  • For example, pfizer viagra free two independent experiments have shown that immunization with a syngeneic serum albumin conjugate of a NSAID (diflunisal and tolmetin) acyl glucuronide stimulated an antibody response in rodents (181,142). The addition of sera from patients with clometacine hepatitis to cultured human hepatocytes that had been exposed to clometacine resulted in hepatocellular injury when autologous lymphoid cells were added , for example. It is only in few cases that there is evidence that these antibodies may play a causative role in cell-mediated toxicity.

    They do not, 382 Boelsterli however, provide evidence that these antibodies are indeed causally involved in an aberrant immune response in the liver. These studies pfizer viagra free show that self-proteins covalently modified by incubation with a reactive NSAID glucuronide can be immunogenic. Antibodies may bind to alkylated membrane proteins on the cell surface and induce cell lysis through complement or killer cells, first.

    Although, in some cases, such antibodies against NSAID-altered peptides have indeed been found, the pathophysiological significance of antibodies is not clear. In particular, it is not clear whether they are causally involved in the killing of target cells or merely markers for antigenicity.
