Leukocyte adhesion deficiency is an immunodeficiency disorder in which white blood cells (leukocytes) do not function normally, causing frequent soft-tissue infections. This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. Researchers are studying whether gene therapy, the implanting of healthy copies of the ITGB2 gene into the blood stem cells of individuals with LAD1 can potentially cure the disorder. PDF A Brief Stocktake of the Deep Geothermal Projects in Bavaria, Germany [1, 2] The clinical picture is characterized by marked leukocytosis and localized bacterial infections that are difficult to detect until they have progressed to an extensive level secondary to lack of leukocyte recruitment at the site of infection.Thus the infections in patients with leukocyte adhesion deficiency act .
