Langerin is a natural barrier to HIV-1 transmission by Langerhans cells
Human immunodeficiency virus-1 (HIV-1) is primarily transmitted sexually. Dendritic cells (DCs) in the subepithelium transmit HIV-1 to T cells through the C-type lectin DC-specific intercellular… Expand

The Dendritic Cell-Specific Adhesion Receptor DC-SIGN Internalizes Antigen for Presentation to T Cells1
Dendritic cells (DCs) capture Ags or viruses in peripheral tissue to transport them to lymphoid organs to induce cellular T cell responses. Recently, a DC-specific C-type lectin was identified,… Expand

Melanomas require HEDGEHOG-GLI signaling regulated by interactions between GLI1 and the RAS-MEK/AKT pathways
Melanoma is one of the most aggressive cancers, and its incidence is increasing. These tumors derive from the melanocyte lineage and remain incurable after metastasis. Here we report that SONIC… Expand

Mechanism of Nef‐induced CD4 endocytosis: Nef connects CD4 with the μ chain of adaptor complexes
The Nef protein of primate lentiviruses down‐regulates the cell surface expression of CD4 and probably MHC I by connecting these receptors with the endocytic machinery. Here, we reveal that Nef… Expand

Nef-Induced CD4 and Major Histocompatibility Complex Class I (MHC-I) Down-Regulation Are Governed by Distinct Determinants: N-Terminal Alpha Helix and Proline Repeat of Nef Selectively Regulate MHC-I…
ABSTRACT The Nef protein of primate lentiviruses triggers the accelerated endocytosis of CD4 and of class I major histocompatibility complex (MHC-I), thereby down-modulating the cell surface… Expand

Dangerous liaisons at the virological synapse.
Cell-to-cell viral transmission facilitates the propagation of HIV-1 and human T cell leukemia virus type 1. Mechanisms of cell-to-cell transmission by retroviruses were not well understood until the… Expand

HIV‐1 Trafficking to the Dendritic Cell–T‐Cell Infectious Synapse Uses a Pathway of Tetraspanin Sorting to the Immunological Synapse
Dendritic cells (DCs) are essential components of the early events of HIV infection. Here, we characterized the trafficking pathways that HIV‐1 follows during its capture by DCs and its subsequent… Expand

The downregulation of CD4 and MHC‐I by primate lentiviruses: a paradigm for the modulation of cell surface receptors
Summary: The human and simian immunodeficiency viruses (HIV and SIV) downregulate the cell surface expression of CD4. their primary receptor, and of class I histocompatibility complex (MHC‐I), a… Expand

Dendritic Cell-Specific Intercellular Adhesion Molecule 3-Grabbing Nonintegrin/CD209 Is Abundant on Macrophages in the Normal Human Lymph Node and Is Not Required for Dendritic Cell Stimulation of…
The C-type lectin dendritic cell-specific ICAM 3-grabbing nonintegrin (DC-SIGN)/CD209 efficiently binds several pathogens, including HIV-1. DC-SIGN is expressed on monocyte-derived DCs in culture,… Expand

DC-SIGN–mediated Infectious Synapse Formation Enhances X4 HIV-1 Transmission from Dendritic Cells to T Cells
Dendritic cells (DCs) are essential for the early events of human immunodeficiency virus (HIV) infection. Model systems of HIV sexual transmission have shown that DCs expressing the DC-specific… Expand
