TL;DR: It is shown that, independently of the transporter associated with antigen processing, gpUL40 can up-regulate expression of HLA-E, which protects targets from NK cell lysis, which is up-regulated by HCMV.
Abstract: The nonclassical major histocompatibility complex (MHC) class I molecule HLA-E inhibits natural killer (NK) cell–mediated lysis by interacting with CD94/NKG2A receptors. Surface expression of HLA-E depends on binding of conserved peptides derived from MHC class I molecules. The same peptide is present in the leader sequence of the human cytomegalovirus (HCMV) glycoprotein UL40 (gpUL40). It is shown that, independently of the transporter associated with antigen processing, gpUL40 can up-regulate expression of HLA-E, which protects targets from NK cell lysis. While classical MHC class I molecules are down-regulated, HLA-E is up-regulated by HCMV. Induction of HLA-E surface expression by gpUL40 may represent an escape route for HCMV.

TL;DR: At 1 year, surgery and best medical therapy improved patient self-reported quality of life more than best medical Therapy alone in patients with advanced Parkinson's disease, but surgery is not without risk and targeting of patients most likely to benefit might be warranted.
Abstract: Summary Background Surgical intervention for advanced Parkinson's disease is an option if medical therapy fails to control symptoms adequately. We aimed to assess whether surgery and best medical therapy improved self-reported quality of life more than best medical therapy alone in patients with advanced Parkinson's disease. Methods The PD SURG trial is an ongoing randomised, open-label trial. At 13 neurosurgical centres in the UK, between November, 2000, and December, 2006, patients with Parkinson's disease that was not adequately controlled by medical therapy were randomly assigned by use of a computerised minimisation procedure to immediate surgery (lesioning or deep brain stimulation at the discretion of the local clinician) and best medical therapy or to best medical therapy alone. Patients were analysed in the treatment group to which they were randomised, irrespective of whether they received their allocated treatment. The primary endpoint was patient self-reported quality of life on the 39-item Parkinson's disease questionnaire (PDQ-39). Changes between baseline and 1 year were compared by use of t tests. This trial is registered with Current Controlled Trials, number ISRCTN34111222. Findings 366 patients were randomly assigned to receive immediate surgery and best medical therapy (183) or best medical therapy alone (183). All patients who had surgery had deep brain stimulation. At 1 year, the mean improvement in PDQ-39 summary index score compared with baseline was 5·0 points in the surgery group and 0·3 points in the medical therapy group (difference −4·7, 95% CI −7·6 to −1·8; p=0·001); the difference in mean change in PDQ-39 score in the mobility domain between the surgery group and the best medical therapy group was −8·9 (95% CI −13·8 to −4·0; p=0·0004), in the activities of daily living domain was −12·4 (−17·3 to −7·5; p Interpretation At 1 year, surgery and best medical therapy improved patient self-reported quality of life more than best medical therapy alone in patients with advanced Parkinson's disease. These differences are clinically meaningful, but surgery is not without risk and targeting of patients most likely to benefit might be warranted.

TL;DR: The IMGT/HLA Database is a specialist database for sequences of the human major histocompatibility (MHC) system that includes all the HLA sequences officially recognised and named by the WHO Nomenclature Committee for Factors of the Hla System.
Abstract: The IMGT/HLA Database is a specialist database for sequences of the human major histocompatibility (MHC) system. It includes all the HLA sequences officially recognised and named by the WHO Nomenclature Committee for Factors of the HLA System. The database provides users with online tools and facilities for the retrieval and analysis of these sequences. These include allele reports, alignment tools and a detailed database of all source cells. The online IMGT/HLA submission tool allows the submission of both new and confirmatory allele sequences directly to the WHO Nomenclature Committee for Factors of the HLA System. The latest version (release 1.4.1, November 1999) contains 1,015 HLA alleles from over 2,270 component sequences derived from the EMBL/GenBank/DDBJ databases. From its release in December 1998 until December 1999 the IMGT/HLA website received approximately 100,000 hits. The database currently focuses on the human major histocompatibility complex but will be used as a model system to provide specialist databases for the MHC sequences of other species.
