Studies of granulocyte chemotaxiswere Higashi mink generated normal performed in mink with the Chediakamounts of chemotactic factors. The Higashi syndrome. In vivo migration cellular defect in leukocyte chemotaxis of leukocytes to an inflammatory site in mink is comparable to that observed was reduced in the affected animals. in humans with the Chediak-Higashi In vitro studies documented a cons...
This case series reports the various treatment modalities to treat multiple recessions. Gingival recession is a widespread clinical manifestation affecting single or root surfaces at all teeth types. Periodontal reconstructive surgery consists of mucogingival procedures. The primary goal these procedures benefit periodontal health through reconstruction lost hard and soft tissues, by preventing...
ICAM-2 has been implicated in leukocyte transmigration in vitro, but there is little in vivo evidence to support this. To address this, neutrophil migration was investigated in ICAM-2–deficient mice (KO) and in wild-type (WT) mice treated with an anti–ICAM-2 blocking monoclonal antibody (mAb) (3C4). In a peritonitis model, IL-1 –induced accumulation of neutrophils was significantly reduced in m...
Transplantation of normal bone marrow to mice with the Chediak-Higashi syndrome (CHS) resulted in normal granulopoiesis and a reversal of their increased susceptibility to challenge with intravenous Candida albicans. These findings suggest that (1) the leukocyte defect in CHS can be reversed by marrow transplantation and (2) the mechanism for increased susceptibility to infection in these anima...
Human populations are rarely exposed to one pathogen alone. Particularly in high incidence regions such as sub-Saharan Africa, concurrent infections with more than one pathogen represent a widely underappreciated public health problem. Two of the world's most notorious killers, malaria and tuberculosis, are co-endemic in impoverished populations in the tropics. However, interactions between bot...
BACKGROUND Ulcerative colitis (UC) is widely viewed as a leukocyte-mediated disorder. Although strong evidence implicates an exuberant response to microbial components in its pathogenesis, no intrinsic immune defect has been identified and the underlying pathogenic mechanisms remain obscure. METHODOLOGY/PRINCIPAL FINDINGS The acute immune response to bacterial injection was determined in UC p...
Leukocyte Adhesion Deficiency Type II (LAD II) is a recently described syndrome and the two patients with this defect lack fucosylated glycoconjugates. These glycoconjugates include the selectin ligand, sialyl LewisX, and various fucosylated blood group antigens. To date, the molecular anomaly in these patients has not been identified. We localized the defect in LAD II to the de novo pathway of...
Polymorphonuclear leukocyte (PMNL) chemotaxis studies of 32 patients with localized juvenile periodontitis (periodontosis or LJP), 10 adult patients with a history of LJP (post-LJP), 8 patients with generalized juvenile periodontitis (GJP), and 23 adults with moderate to severe periodontitis were performed: (i) to determine the prevalence of a PMNL chemotaxis defect in a large group of LJP pati...
Glucose 6-phoshphate dehydrogenase is X-chromosome linked that expressed in all tissues. This is the first enzyme of pentose phosphate pathway were 5-carbon sugar Ribose and NADPH were synthesized by coupled oxidation /reduction reactions and this enzyme is a highly polymorphic enzyme in humans. G6PD deficiency are shown to be the cause of haemolytic effect of Fava beans and primaquine. It soon...
