interaction between her-2 and hormone receptors in breast cancer

introduction: breast cancer is the most common malignancy with more than one million new cases diagnosed annually all around the world. its growth is mostly regulated by steroid hormones such as estrogen and peptide growth factors in interaction with epidermal growth factor 1 and 2. methods and materials: in this study, 237 patients who had consulted the oncology clinic of tabriz university of ...

HIV-1 preferentially binds receptors copatched with cell-surface elastase.

Human leukocyte elastase (HLE) interacts with HIV-1 glycoprotein (gp)41, suggesting a nonenzymatic receptor function for HLE in the context of HIV-1. HLE is found localized to the cell surface, but not granules in HIV permissive clones, and to granules, but not the cell surface of HIV nonpermissive clones. Inducing cell-surface HLE expression on HLE null, HIV nonpermissive clones permits HIV in...

HIV-1 receptors and cell tropism.

HIV virus particles interact with several receptors on cell surfaces. Two receptors, CD4 and a co-receptor act sequentially to trigger fusion of viral and cellular membranes and confer virus entry into cells. For HIV-1, the chemokine receptor CCR5 is the predominant co-receptor exploited for transmission and replication in vivo. Variants that switch to use CXCR4 and perhaps other co-receptors e...

Myeloid Cell Interaction with HIV: A Complex Relationship

Cells of the myeloid lineage, particularly macrophages, serve as primary hosts for HIV in vivo, along with CD4 T lymphocytes. Macrophages are present in virtually every tissue of the organism, including locations with negligible T cell colonization, such as the brain, where HIV-mediated inflammation may lead to pathological sequelae. Moreover, infected macrophages are present in multiple other ...
