We have localized several major extracellular matrix protein receptors in the specific granules of human polymorphonuclear (PMN) and monocytic leukocytes using double label immunoelectron microscopy (IEM) with ultrathin frozen sections and colloidal-gold conjugates. Rabbit antibodies to 67-kD human laminin receptor (LNR) were located on the inner surface of the specific granule membrane and wit...

background: toxocariasis is a prevalent zoonosis disease caused by the closely related nematode species toxocara canis and toxocara cati which parasitise canidae and felidae respectively. in paratenic hosts, larvae of these worms cause multiple organ damage. however, how these paratenic hosts response to these worms and whether any common biomarker can be applied for diagnosis are still unclear...

introduction: human leukocyte antigen (hla) genes are the most polymorphic loci in the human genome. they predict the outcome of transplantation by detecting self from non-self antigens. the best use of hla typing is to find a hla-match donor for bmt candidate patients. evidence suggests that matching unrelated donors and recipients for hla-a, -b and -drb1 loci is a prediction for an improved o...

selective iga deficiency (igad) (serum iga concentration of pcr was used to type hla b, dr, and dq alleles in 29 iranian individuals with igad and 299 swedish individuals with igad. the results indicate a strong association with the hla b14, dr1 alleles in iranian subjects and hla b8, b12, b13, b14, b40, dr1, dr3, dr7, dq2 and dq5 alleles in swedish subjects. differences in hla association of i...

hepatitis b virus (hbv) infection and its sequelae such as cirrhosis and hepatocellular carcinoma has remained a serious public health problem throughout the world. the who strategy for effective control of hbv infection and its complications is mass vaccination of neonates and children within the framework of expanded programme on immunization (epi). vaccination with hepatitis b surface antige...

Human leukocyte antigens (HLA) are gene products found in the major histocompatibility complex, aiding differentiation of “self” from “non-self” antigens, and is crucial for communication between immune cells human body. HLA-B27, specific, has a strong interrelation with different types Spondyloarthritis (SpA). The aim this study to frequency HLA-B27 suspected patients presenting axial peripher...

OBJECTIVES Although previous studies have investigated the effect of human leukocyte antigen matching on long-term outcomes after heart transplants, its role in the prognosis after a heart transplant remains unclear, particularly with respect to short-term survival. MATERIALS AND METHODS We evaluated the human leukocyte antigen mismatch on in-hospital mortality of 158 consecutive patients who...

OBJECTIVE This study aimed to verify the association between human leukocyte antigens and the bcr-abl fusion protein resulting from t(9;22)(q34;q11) in chronic leukemia myeloid and acute lymphoblastic leukemia patients. METHODS Forty-seven bcr-abl positive individuals were evaluated. Typing was performed bymicrolymphocytotoxicity and molecular biological methods (human leukocyte antigens Clas...

Background & Objective: Unexplained recurrent spontaneous abortion (URSA) is defined as an unknown cause of occurrence of three or more clinically detectable pregnancy losses before 20 weeks of gestation, but it occurs presumably as a result of the immune system dysfunctions. We supposed that the disruption of semen or spermatozoa might be responsible for the dysfunction of the...
