Several studies demonstrated a relevant role of polymorphisms located within the HLA-B and -C loci and the Killer Immunoglobulin Receptors (KIRs) 3DL1 and 3DS1 in controlling HIV-1 replication. KIRs are regulatory receptors expressed at the surface of NK and CD8+ T-cells that specifically bind HLA-A and -B alleles belonging to the Bw4 supratype and all the(More)
BACKGROUND Multiple target molecular monitoring of minimal residual disease in neuroblastoma (NB) patients may increase sensitivity and overcome tumor heterogeneity. However, multiple target analysis is costly and time consuming, thus improvement with respect to single target monitoring needs to be achieved. PROCEDURES Italian patients with localized NB(More)
Cellular immunity against cytomegalovirus (CMV) is essential for recovery from infection and control of viral latency. In immunocompromised hosts, this balance between CMV and cellular immunity is lost. Accordingly, restoration of the CD8 compartment specific for CMV is beneficial for immunocompromised patients. It is clear that CMV-specific CD4 cells(More)
The effect of anti-CD69 monodonal antibodies (mAbs) on the induction of the cytolytic activity in different types of lymphoid effector cells has been investigated. Three anti-CD69 mAbs, including the reference mAb MLR3 and two new mAbs (c227 and 31C4), have been used. All cloned CD3-CD16 + natural killer (NK) cells belonging to different subsets (as defined(More)
BACKGROUND Since there is no validated assay to monitor disease in children with neuroblastoma (NB), we tested whether NB specific cell-free RNA could be detected in their plasma samples. Moreover, with the aim of reducing patients' discomfort, we compared this assay to a recently standardized procedure that uses a larger amount of whole blood. PROCEDURES(More)
Bullous pemphigoid (BP) is an autoimmune skin disease that occurs mainly in elderly patients; onset of BP is rare in childhood. Inflammatory bowel diseases (IBD), by contrast, have a pediatric onset in 25% of presenting cases, requiring expert multidisciplinary management. Here we report a pediatric case of IBD (involving stomach, duodenum, ileum, and(More)
BACKGROUND Virus-specific CD4 and CD8 T lymphocytes from HLA-matched donors are effective for treatment and prophylaxis of viral infections in immune-compromised recipients of hematopoietic stem cell transplant recipients. Adoptive immune reconstitution is based on selection of specific T cells or on generation of specific T-cell lines from the graft donor.(More)
BACKGROUND The monitoring of near miss errors, in other words events that cannot be classified as substantial errors, but whose occurrence suggests that there is probably a critical point in a working procedure, can be useful in order to prevent these 'almost errors' from occurring again or to prevent them evolving into 'relevant errors'.
