Single and multiple high-dose administrations of methamphetamine (METH) differentially decrease dopamine (DA) transporter (DAT) function, as assessed by measuring [(3)H]DA uptake into rat striatal synaptosomes prepared 1 h after treatment. Prevention of METH-induced hyperthermia attenuated the decrease in DAT activity induced by multiple injections of the stimulant. Likewise, this decrease was ...
We investigated the associations between methamphetamine (meth) use, immune function, and the dynamics of HIV and cytomegalovirus [CMV] in the blood and genital tract of HIV-infected ART-suppressed subjects. Self-reported meth use was associated with increased CD4(+) and CD8(+) T-cell proliferation (Ki67(+), p < 0.005), CD4(+) T-cell activation (CD45RA(-)CD38(+), p = 0.005) and exhaustion (PD-1...
Single large doses of methamphetamine (METH) cause endoplasmic reticulum (ER) stress and mitochondrial dysfunctions in rodent striata. The dopamine D(1) receptor appears to be involved in these METH-mediated stresses. The purpose of this study was to investigate if dopamine D(1) and D(2) receptors are involved in ER and mitochondrial stresses caused by single-day METH binges in the rat striatum...
The finding that class I major histocompatibility complex (MHC)-restricted cytotoxic T lymphocytes (CTL) recognize peptide antigens (epitopes) bound to class I MHC molecules has accelerated efforts to identify CTL-defined tumor peptides for the development of peptide-based cancer immunotherapy. The Meth A sarcoma is probably one of the best studied of all murine tumors. It is extremely lethal u...
BACKGROUND Methamphetamine (METH), an abused illicit drug, disrupts many cellular processes, including energy metabolism, spermatogenesis, and maintenance of oxidative status. However, many components of the molecular underpinnings of METH toxicity have yet to be established. Network analyses of integrated proteomic, transcriptomic and metabolomic data are particularly well suited for identifyi...
Methamphetamine (Meth) abusing represents a major public health problem worldwide. Meth has long been known to induce neurotoxicity. However, the mechanism is still remained poorly understood. Growing evidences indicated that the voltage-gated potassium channels (Kv) were participated in neuronal damage and microglia function. With the whole cell patch clamp, we found that Meth significantly in...
BACKGROUND Methamphetamine (Meth) abuse continues to be a major illicit drug of abuse. Neuroimaging findings suggest that Meth is neurotoxic and may alter various brain structures, but the effect of Meth on the aging brain has not been studied. AIM The aim was to determine regional volumes of cortical gray matter in the brains of adult Meth users versus healthy control subjects, and their int...
We have studied two related proteins that contain a repeated amino acid motif homologous to the anti-angiogenic type 1 repeats of thrombospondin-1 (TSP1). Complete sequence analysis revealed no other similarities with TSP1, but identified unique signal sequences, as well as metalloprotease and disintegrin-like domains in the NH(2) termini. We named these proteins METH-1 and METH-2 due to the no...
The psychostimulant methamphetamine (METH) is an addictive drug of abuse. The neuropeptide oxytocin has been shown to modulate METH-related reward and METH-seeking behaviour. Recent findings implicated the subthalamic nucleus (STh) as a key brain region in oxytocin modulation of METH-induced reward. However, it is unclear if oxytocin acts in this region to attenuate relapse to METH-seeking beha...
