BACKGROUND: Donor lymphocyte infusion (DLI) is currently standard therapy for relapse of malignancies after allogeneic BMT. Several observations suggest that both normal and leukemic progenitor cells of host origin constitute effective target cells for donor-derived lymphocytes. To prevent relapse of sickle cell disease (SCD), a child with evidence of decreasing mixed chimerism received DLIs 8 months after allogeneic BMT for SCD. CASE REPORT: A 4-year-old child who was homozygous for SCD underwent a transplantation of bone marrow from his fully HLA-matched sister. Routine detection of sex chromosomes in bone marrow cells evidenced decreasing mixed chimerism, which heralded a probably imminent recurrence of the disease. The patient received two DLIs in graded incremental doses on Days 234 and 267. One month later, he developed grade 2 acute GVHD that responded well to corticosteroids and cyclosporine. RESULTS: DLI resulted in complete donor chimerism within 2 months of the second infusion. Now, 2 years after the second DLI, the patient is in excellent condition, with normal Hb and excellent growth and development. CONCLUSION: This is the first report of successful use of DLI in a patient with probable imminent SCD recurrence after allogeneic BMT. It shows that DLI can displace residual host HPCs in case of recurrence of nonmalignant disease after allogeneic BMT. [less ▲]

This study examined interactions between cocaine and drugs that act as direct agonists at subtypes of "D2-like" dopamine receptors. The drugs 7-OH-DPAT, quinpirole and RU24213 were studied alone and in combination with cocaine for their effects on locomotor activity in non-habituated mice. Locomotor activity was measured by photobeam crossings over 140 min. At the doses given (7-OH-DPAT: 0.006-6.4 mg/kg; quinpirole: 0.001-1 mg/kg; RU24213: 0.008-8 mg/kg) all three direct agonists dose-dependently reduced locomotor activity throughout the test, whereas cocaine (0.6-20 mg/kg) produced dose-related hyperactivity. Next, for each direct agonist, a series of doses was selected (up to threshold behaviourally-active doses) as pretreatments to a sub-maximally stimulant dose of cocaine (15 mg/kg). 7-OH-DPAT and quinpirole did not modulate the effects of cocaine; RU24213 produced, at best, a very modest attenuation of the effects of cocaine. Finally, a series of cocaine doses (below stimulant threshold) was given before a single dose of each direct agonist (the lowest dose to reduce activity significantly). Cocaine did not reliably alter the hypoactivity produced by any of the D2-like agonists. By demonstrating negligible interactions between cocaine and D2-like agonists, the results fail to demonstrate any necessary involvement of D2-like receptors in one of the behavioural effects of cocaine.

Dopamine (DA) facilitates male sexual behavior and modulates aromatase activity in the quail preoptic area (POA). Aromatase neurons in the POA receive dopaminergic inputs, but the anatomical substrate that mediates the behavioral and endocrine effects of DA is poorly understood. Intracellular recordings showed that 100 muM DA hyperpolarizes most neurons in the medial preoptic nucleus (80%) by a direct effect, but depolarizes a few others (10%). DA-induced hyperpolarizations were not blocked by D1 or D2 antagonists (SCH-23390 and sulpiride). Extracellular recordings confirmed that DA inhibits the firing of most cells (52%) but excites a few others (24%). These effects also were not affected by DA antagonists (SCH-23390 and sulpiride) but were blocked by alpha(2)-(yohimbine) and alpha(1)-(prazosin) noradrenergic receptor antagonists, respectively. Two dopamine-beta-hydroxylase (DBH) inhibitors (cysteine and fusaric acid) did not block the DA-induced effects, indicating that DA is not converted into norepinephrine (NE) to produce its effects. The pK(B) of yohimbine for the receptor involved in the DA- and NE-induced inhibitions was similar, indicating that the two monoamines interact with the same receptor. Together, these results demonstrate that the effects of DA in the POA are mediated mostly by the activation of alpha(2) (inhibition) and alpha(1) (excitation) adrenoreceptors. This may explain why DA affects the expression of male sexual behavior through its action in the POA, which contains high densities of alpha(2)-noradrenergic but limited amounts of DA receptors. This study thus clearly demonstrates the existence of a cross talk within CNS catecholaminergic systems between a neurotransmitter and heterologous receptors. [less ▲]

A commonly held view is that dopamine exerts its effects via binding to D1- and D2-dopaminergic receptors. However, recent data have emerged supporting the existence of a direct interaction of dopamine with adrenergic but this interaction has been poorly investigated. In this study, the pharmacological basis of possible in vivo interactions between dopamine and alpha(2)-adrenergic receptors was investigated in zebra finches. A binding competition study showed that dopamine displaces the binding of the alpha(2)-adrenergic ligand, [(3)H]RX821002, in the brain. The affinity of dopamine for the adrenergic sites does not differ between the sexes and is 10- to 28-fold lower than that for norepinephrine. To assess the anatomical distribution of this interaction, binding competitions were performed on brain slices incubated in 5nM [(3)H]RX821002 in the absence of any competitor or in the presence of norepinephrine [0.1microM] or dopamine [1microM]. Both norepinephrine and dopamine displaced the binding of the radioligand though to a different extent in most of the regions studied (e.g., area X, the lateral part of the magnocellular nucleus of anterior nidopallium, HVC, arcopallium dorsale, ventral tegmental area and substantia grisea centralis) but not in the robust nucleus of the arcopallium. Together these data provide evidence for a direct interaction between dopamine and adrenergic receptors in songbird brains albeit with regional variation. [less ▲]
