Type 1 diabetes (T1D) results from gradual alteration of insulin-secreting pancreatic b-cells. When most b-cells are destroyed and/or nonfunctional, patients are unable to regulate hyperglycemia and clinical signs appear (1). Although T cells play a key role in b-cell destruction, other immune cells are also involved in T1D physiopathology (2). Both Foxp3(More)
In the setting of chronic hepatitis C virus (HCV) infection, changes in natural killer (NK) cells have been shown to reflect activation in response to virus stimulation. The contribution of individual natural cytotoxicity receptors to HCV infection remains to be clarified. NKp44 is the sole specific natural cytotoxicity receptor expressed only on activated(More)
OBJECTIVE HIV-infected immunological nonresponders (InRs) patients fail to show satisfactory CD4+ T-cell recovery despite virologically effective HAART. We propose that NKp44L, the cellular ligand of an activating natural killer (NK) receptor, expressed only on uninfected bystander CD4+ T cells from HIV-1 infected patients, could play a major role in this(More)
Type 1 diabetes (T1D) is an autoimmune disease that results from the destruction of pancreatic β-cells by the immune system that involves innate and adaptive immune cells. Mucosal-associated invariant T cells (MAIT cells) are innate-like T-cells that recognize derivatives of precursors of bacterial riboflavin presented by the major histocompatibility(More)
In the 1990 s, the variability of responses to human immunodeficiency virus (HIV) could only be tracked by phenotypic criteria such as the number of CD4T lymphocytes, the occurrence of opportunistic infection, the disease free survival without treatment. In 1996, the viral load is the leading phenotype for genetic studies. Ever since, thanks to a better(More)
Urinary protein electrophoresis analysis (UPE) is an essential investigation for the study of abnormal proteins in urines. The interpretation of this analysis must be comprehensive and relevant. Indeed, UPE is often requested by clinicians and may have an important impact in patient's management. This paper presents two cases with free light chains showing(More)
