OBJECTIVES The incidence of hypersensitivity reactions (HR) is increased in patients treated with multiple courses of carboplatin. The purposes of this investigation were to evaluate the effectiveness of a 12-step desensitization protocol and to characterize the immune mechanism of carboplatin HR. METHODS We analyzed 10 consecutive patients who had documented HR to carboplatin and in whom con...

BACKGROUND AND OBJECTIVE The immune system is an important player in the pathophysiology of periodontitis. The brain controls immune responses via neural and hormonal pathways, and brain-neuro-endocrine dysregulation may be a central determinant for pathogenesis. Our current knowledge also emphasizes the central role of sensory nerves. In line with this, we wanted to investigate how desensitiza...

The cross-regulation of G protein-coupled receptors (GPCRs) plays an important role in the immune response. Studies from several laboratories have suggested that a hierarchy of sensitivities to cross-desensitization exists for the chemoattractant GPCRs. We carried out experiments to study the capacity of the formyl peptide receptor-1 (FPR1) to desensitize chemokine receptors CCR1 and CCR2. Our ...

Immune-to-brain communication is essential for an individual to aptly respond to challenging internal and external environments. However, the specificity by which the central nervous system detects or 'senses' peripheral immune challenges is still poorly understood. In contrast to post-mortem c-Fos mapping, we recorded neural activity in vivo in two specific cortico-limbic regions relevant for ...

BACKGROUND Few options for transplantation currently exist for patients highly sensitized to HLA. This exploratory, open-label, phase 1-2, single-center study examined whether intravenous immune globulin plus rituximab could reduce anti-HLA antibody levels and improve transplantation rates. METHODS Between September 2005 and May 2007, a total of 20 highly sensitized patients (with a mean [+/-...
