Human anti-human leukocyte antigen (HLA) antibodies were assessed for neutralizing activity against human immunodeficiency virus type 1 (HIV-1) carrying HLA alleles with matching specificity. Multiparous women carrying anti-HLA antibodies were identified. Plasma samples from those women were confirmed as having antibodies that specifically bound to HLA proteins expressed on the peripheral blood...
Anti-HLA and Anti-MICA Antibodies in Liver Transplant Recipients: Effect on Long-Term Graft Survival
OBJECTIVE Presence of anti-HLA antibodies has a well-known impact on kidney grafts survival; however their role in liver transplantation has not been fully elucidated. We conducted a 7-year prospective study to show correlation between presence of anti-HLA and anti-MICA antibodies and liver graft survival. METHODS Blood samples from 123 liver transplant recipients were collected during patien...
Autoimmune reaction in Type 1 Diabetes Mellitus (T1DM) is caused by genetic and environmental factors. The genes HLA-DQA1 HLA-DQB1 are strongly associated with T1DM. Other established markers of T1DM were Zinc Transporter 8 Antibody (ZnT8), Glutamic Acid Decarboxylase Antibody-65 (GAD65), C-peptide. This study aims to analyze ZnT8, GAD65, HLA-DQA1, HLA-DQB1, C-peptide Indonesian children A cros...
We have studied the interaction of HLA class I antigens with alloreactive cytotoxic T lymphocytes and monoclonal antibodies using site-directed mutagenesis and expression of an HLA-Aw68.1 gene. Two mutants containing distinct substitutions at polymorphic residues near the NH2-terminal end of the alpha 2 domain were made. One mutant with substitutions at positions 95 and 97 corresponding to resi...
In the Trial to Reduce Alloimmunization to Platelets (TRAP) study, 101 of 530 participants became refractory to platelet transfusions without evidence of HLA or human platelet antigen (HPA) antibodies. We used a more sensitive bead-based assay to detect and quantify HLA antibodies and a qualitative solid-phase enzyme-linked immunosorbet assay for HPA to determine whether low-level antibodies co...
The involvement of immunologic and nonimmunologic events in long-term kidney allograft failure is difficult to assess. The development of HLA antibodies after transplantation is the witness of ongoing reactivity against the transplant, and several studies have suggested that the presence of HLA antibodies correlates with poor graft survival. However, they have not discriminated between donor-sp...
Introduction. The Implementation of immunotherapy in cancer requires a thorough analysis the biological characteristics tumor. Therefore, study tumor immunophenotype is leading scientific direction. Molecules major histocompatibility complex are considered as promising markers for evaluating possibility using immunotherapy. Objective. To primary molecular subtypes breast and analyze it dependin...
BACKGROUND Anti-HLA antibodies hamper successful transplantation, and activation of the complement cascade is involved in antibody-mediated rejection. We investigated whether the complement-binding capacity of anti-HLA antibodies plays a role in kidney-allograft failure. METHODS We enrolled patients who received kidney allografts at two transplantation centers in Paris between January 1, 2005...
BACKGROUND/AIMS Anti-ganglionic nicotinic acetylcholine receptor (gAChR) antibodies are observed in autoimmune diseases, as well as in patients with autoimmune autonomic ganglionopathy. However, the genetic background of anti-gAChR antibodies is unclear. Here, we investigated HLA alleles in autoimmune hepatitis (AIH) patients with or without anti-gAChR antibodies. METHODOLOGY/PRINCIPAL FINDIN...
OBJECTIVE The relationship between human leukocyte antigens class II (HLA) and antinuclear antibodies was investigated in Jamaican patients with Systemic Lupus Erythematosus (SLE). METHODS Samples of blood of 82 patients with SLE and 75 healthy controls were tested for antinuclear antibodies using the fluorescent antinuclear antibody (FANA) test, counterimmunoelectrophoresis (CIEP) and the Cr...
