Asthma is characterized by the presence of activated CD4+ cells in the airways. We hypothesized that the newly characterized cytokine interleukin (IL)-16 is involved in the pathogenesis of asthma through its ability to selectively induce CD4+ cell recruitment within the inflamed bronchial wall. We investigated the expression of IL-16 in bronchial biopsies(More)
Lymphocyte chemoattractant factor (LCF) is a tetrameric glycoprotein of 56,000 relative molecular mass produced by activated T lymphocytes. LCF binds to CD4 and has previously been found to stimulate migration of CD4+ lymphocytes and monocytes. Because human eosinophils, like T cells and monocytes, express CD4, we examined functional responses of(More)
Interleukin-16 (IL-16) was the first described T lymphocyte chemoattractant. It has since been shown that IL-16 also functions as a primer of T cell proliferation, a modulator of inflammatory and immune responses, a stimulus of B cell differentiation and an inhibitor of Human immunodeficiency virus (HIV) replication. Its precursor, Prointerleukin-16(More)
Cell activation by phytohaemagglutinin, phorbol ester and by the supernatant of phytohaemagglutinin-stimulated peripheral blood mononuclear cells induces the expression and cytopathic effects of latent human immunodeficiency virus type-1 (HIV-1) in vitro. The lymphocyte surface protein CD4 has been identified as a receptor for HIV-1 and binds the viral(More)
Epithelial cells from individuals with asthma or from allergen-have been implicated in both initiation and perpetuation sensitized mice contain intracellular interleukin (IL)-16 protein, of the immune response to antigen (4), and therefore play not present in epithelial cells from individuals without asthma a central role in allergic airway(More)
Somatic mutation-mediated evolution of herbicide resistance in the non-indigenous invasive plant hydrilla (Hydrilla verticillata). A summary of future management recommendations from the hydrilla summit in Florida. Performance of two established biological controls agents on susceptible and fluridone resistant genotypes of the aquatic weed hydrilla.(More)
