Celiac disease is a chronic autoimmune condition triggered by dietary gluten in genetically predisposed individuals and the treatment is a strict gluten-free diet. The major predisposing genes are HLA-DQA1 and HLA-DQB1, but these are not sufficient for disease development. One of the candidate genes worth studying is interleukin (IL)-15 gene, together with its specific receptor, IL-15Rα, as they participate in promoting lymphocyte signaling and survival, and the establishment of appropriate conditions for villous atrophy, then acting as key players in the immunopathogenesis of CD...

BACKGROUND: In this report, we analyzed the number and activation profiles of T cells in EBV-HLH patients and assessed their value for the diagnosis of EBV-HLH. METHODS: We compared the quantity of CD4+ T cells and CD8+ T cells in peripheral blood among HLH patients, a sepsis group and healthy controls. We then analyzed variations in the activation marker in CD4+ T cells and CD8+ T cells. RESULTS: The percentage of CD4+ T cells decreased in the EBV-HLH patients compared to healthy controls, which induced significant differences in the ratio of CD4+ T cells/CD8+ T cells...

Although the observation of major histocompatibility complex II (MHCII) receptors on T cells is longstanding, the explanation for this occurrence remains enigmatic. Reports of an inducible, endogenous expression exist, as do studies demonstrating a protein acquisition from other cells by mechanisms including vesicle transfer. Irrespective of origin, the presence of the human MHCII isotype, human leukocyte antigen DR (HLA-DR), potentially identifies a regulatory T cell population. Using an allogeneic mixed lymphocyte culture (MLC) to induce an antigen-specific immune response, the role of antigen-presenting cells (APCs) for the presence of HLA-DR on cluster of differentiation 3(CD3)+ CD4+ T cells was evaluated...

We retrospectively investigated outcomes of haploidentical donor (HID) transplant for adults with standard-risk acute lymphoblastic leukaemia (ALL) in first complete remission (CR1) compared with human leucocyte antigen (HLA)-matched sibling donor (MSD) and HLA-matched unrelated donor (MUD) transplants. A total of 348 adult patients were enrolled, including 127 HID, 144 MSD and 77 MUD recipients. The cumulative incidence of grade II-IV acute graft-versus-host disease (aGVHD) was 39·5%, 24·0% and 40·3% for HID, MSD and MUD, respectively (P = 0·020)...

Genetic variability related to the host immune system has been proposed as one of the most influential factors in the development of diseases caused by HPV. CLINICAL CASE: We report the case of a 5-year-old child in whom chronic laryngeal papillomatosis, probably acquired vertically during labor, was detected. The diagnosis of laryngeal papillomatosis was confirmed with a biopsy after a first surgery to remove the papillomas. The Derkay classification system was used to assess the severity of papillomatosis...

Parkinson Disease (PD) is a complex and heterogeneous neurodegenerative disease characterized by a progressive loss of dopaminergic neurons in the substantia nigra pars compacta and pathological intracellular accumulation of alpha-synuclein (α-syn). In the vast majority of PD patients, the disease has a complex etiology, defined by multiple genetic and environmental risk factors. Common genetic variants in the human leukocyte-antigen (HLA) region have been associated to PD risk and the carriage of these can double the risk to develop PD...

BACKGROUND: Preformed donor-specific human leukocyte antigen antibodies (DSAs) in patients undergoing simultaneous liver and kidney transplantation (SLKT) are an independent risk factor for poorer patient and renal allograft survival. The outcomes of patients highly sensitized (HS) against HLA antigens undergoing SLKT and select HS SLKT recipients undergoing desensitization at a high-volume desensitization center were investigated. METHODS: Seventy-five patients undergoing SLKT at a high-volume desensitization center between January 1, 2001, and December 31, 2015, were retrospectively reviewed...

INTRODUCTION: Kidney transplantation (KTX) has become one of the most effective therapies of choice for pediatric patients with end-stage renal disease (ESRD). The extent to which HLA mismatching influences graft survival following KTX has not been clarified. PATIENTS AND METHODS: The effect of HLA amino acid residue matching on graft survival was assessed in 36 pediatric patients in whom complete donor-recipient HLA data were available. HLA-A, -B, -DR and HLA-A+B+DR loci residue mismatches were separately analyzed...

BACKGROUND: Sensitization is associated with a high rate of post-transplantation rejection. A desensitization protocol using therapeutic plasma exchange (TPE) was proposed to reduce anti-HLA antibody before transplantation, but there has been limited data regarding the efficacy of pretransplantation TPE in highly sensitized deceased-donor kidney transplantation (DDKT). METHODS: A retrospective cohort study of 142 patients who received DDKT was conducted and divided into two groups: a high-panel-reactive antibody (PRA) >50% group and a low-PRA ≤50% group...

CD8(+) T lymphocytes can reduce the production of human immunodeficiency virus 1 (HIV-1) by CD4(+) T cells by cytotoxic and non-cytotoxic mechanisms. To investigate the involvement of human leukocyte antigen (HLA) class I compatibility in anti-HIV responses, we co-cultured primary CD8(+) T cells, isolated from the peripheral blood of HIV-1-infected individuals, with panels of autologous and heterologous acutely HIV-1-infected primary CD4(+) T cells. Altogether, CD8(+) T cell anti-HIV activity was evaluated in more than 200 co-cultures...

Killer immunoglobulin-like receptors (KIR) are transmembrane proteins that regulate NK and T cell subsets by recognizing HLA-I molecules as ligands. The KIR gene family consists of 16 genes, located at chromosome 19q13.4. KIR gene frequencies vary among populations. In Mexico, HLA and genetic ancestry studies show that Mestizo populations have different genetic backgrounds based on admixture with European, African, and Asian ancestry. This study aimed to evaluate the frequencies of KIR genes and genotypes in Guerrero and Jalisco, two Mexican Mestizo populations located in the south and the west of the country, respectively, and to compare these frequencies with those of other populations...

Genomic DNA is damaged at an extremely high frequency by both endogenous and environmental factors. An improper response to DNA damage can lead to genome instability, accelerate the aging process and ultimately cause various human diseases, including cancers and neurodegenerative disorders. The mechanisms that underlie the cellular DNA damage response (DDR) are complex and are regulated at many levels, including at the level of post-translational modification (PTM). Since the discovery of ubiquitin in 1975 and ubiquitylation as a form of PTM in the early 1980s, a number of ubiquitin-like modifiers (UBLs) have been identified, including small ubiquitin-like modifiers (SUMOs), neural precursor cell expressed, developmentally down-regulated 8 (NEDD8), interferon-stimulated gene 15 (ISG15), human leukocyte antigen (HLA)-F adjacent transcript 10 (FAT10), ubiquitin-fold modifier 1 (UFRM1), URM1 ubiquitin-related modifier-1 (URM1), autophagy-related protein 12 (ATG12), autophagy-related protein 8 (ATG8), fan ubiquitin-like protein 1 (FUB1) and histone mono-ubiquitylation 1 (HUB1)...
