Human immunodeficiency virus type 1 (HIV-1) uses the chemokine receptors CCR5 and CXCR4 for entry. Macrophages and microglia (M/M) are the principal productively infected brain cells in HIV encephalopathy (HIVE), and neuronal injury is believed to result both from direct effects of viral proteins and indirect effects mediated by macrophage activation and secretion of neurotoxic products. In vitro, direct injury by the viral envelope glycoprotein gp120 can be mediated by neuronal CXCR4, but most…

Macrophage signaling in HIV-1 infection
TLDR
The role of HIV-1 proteins in the modulation of macrophages signaling will be discussed in regard to the formation of viral reservoirs and macrophage-mediated T cell apoptosis during HIV- 1 infection.
Reviewsignaling in HIV-1 infection
TLDR
The role of HIV-1 proteins in the modulation of macrophage signaling will be discussed in regard to the formation of viral reservoirs and macrophages-mediated T cell apoptosis during HIV- 1 infection.
HIV-1 Gp120 Protein Downregulates Nef Induced IL-6 Release in Immature Dentritic Cells through Interplay of DC-SIGN
TLDR
This study elucidated for the first time the cross-talk of the signaling mechanism of these two viral proteins in immature monocyte derived dentritic cells (immDCs) and implicate that the signaling generated by gp120 and Nef, undergoes a switch-over mechanism that significantly contributes to the pathogenesis of HIV-1 and widens the view on battling the viral infection.
Human Peritoneal Macrophages From Ascitic Fluid Can be Infected by a Broad Range of HIV-1 Isolates
TLDR
It is demonstrated that peritoneal macrophages (PMs) are abundant in ascitic fluid of patients with liver cirrhosis and are susceptible to HIV-1 infection, and is susceptible to receptor-mediated infection by a broad range of HIV strains.
Activation of Cannabinoid Type 2 Receptors Inhibits HIV-1 Envelope Glycoprotein gp120-Induced Synapse Loss
TLDR
Results indicate that cannabinoids prevent the impairment of network function produced by gp120 and, thus, might have therapeutic potential in HAD.
In Vitro and In Vivo Regulation of Pro-inflammatory Cytokines and Drug Efflux Transporters by Signal Transduction Pathways in Glial Cells: Implications in HIV-1 Neuropathogenesis and its Treatment
TLDR
It is demonstrated that gp120-associated TNF-α release resulted in increased Mrp1 functional expression in primary cultures of rat astrocytes and both c-jun Nterminal kinase (JNK) and nuclear factor-кB (NF-κB) pathways were involved.
Regulation of Multidrug Resistance Protein 1 by Tumor Necrosis Factor α in Cultured Glial Cells: Involvement of Nuclear Factor-κB and c-Jun N-Terminal Kinase Signaling Pathways
TLDR
These data suggest that gp120 and TNF-α can up-regulate Mrp1 expression in cultured astrocytes and imply that both NF-κB and JNK signaling are involved inMrp1 regulation during an HIV-1 associated inflammatory response.
Regulation of Neuronal Chemokine Receptor CXCR4 by μ-Opioid Agonists and Its Involvement in NeuroAIDS
TLDR
Current knowledge on the cross-talk between opioid and chemokine receptors in the brain focusing on underlying cellular and molecular mechanisms which might be relevant to HIV neuropathology is reviewed.
HIV Co-receptors: The Brain Perspective
TLDR
The role of chemokines and chemokine receptors in HIV-1 infection and the pathogenesis of AIDS and HIVD is discussed and potential therapeutic strategies are briefly detailed.
Co-receptor signaling in the pathogenesis of neuroHIV
TLDR
This discussion will provide a comprehensive overview of what is known and what remains to be explored in regard to co-receptor signaling and HIV infection, and will emphasize the potential value of HIV co- receptors as a target for future therapeutic development.

Lymphotropic Virions Affect Chemokine Receptor-Mediated Neural Signaling and Apoptosis: Implications for Human Immunodeficiency Virus Type 1-Associated Dementia
TLDR
The results suggest that progeny HIV-1 virions can influence neuronal signal transduction and apoptosis of neurons, astrocytes, and monocyte-derived macrophages.
Macrophage-tropic HIV and SIV envelope proteins induce a signal through the CCR5 chemokine receptor
TLDR
It is shown that recombinant envelope proteins from macrophage-tropic HIV and SIV induce a signal through CCR5 on CD4+ T cells and that envelope-mediated signal transduction through C CR5 induces chemotaxis of T cells.
Localization of HIV-1 co-receptors CCR5 and CXCR4 in the brain of children with AIDS.
TLDR
Findings suggest that CCR5-positive mononuclear cells, macrophages, and microglia contribute to disease progression in the central nervous system of children and adults with AIDS by serving as targets for virus replication.

Microglia Express CCR5, CXCR4, and CCR3, but of These, CCR5 Is the Principal Coreceptor for Human Immunodeficiency Virus Type 1 Dementia Isolates
TLDR
It is found that virus pseudotyped with the DS-br and RC-br envelopes can infect cells transfected with CD4 in conjunction with the G-protein-coupled receptors APJ, CCR8, and GPR15, which have been previously implicated in HIV entry.
HIV-1 gp120 and chemokines activate ion channels in primary macrophages through CCR5 and CXCR4 stimulation.
TLDR
The interaction of HIV-1 gp120 with CCR5 or CXCR4 evokes complex and distinct signaling responses in primary macrophages, and gp120-evoked signals differ from those activated by the coreceptors' chemokine ligands.
Chemokine receptors as HIV-1 coreceptors: roles in viral entry, tropism, and disease.
In addition to CD4, the human immunodeficiency virus (HIV) requires a coreceptor for entry into target cells. The chemokine receptors CXCR4 and CCR5, members of the G protein-coupled receptor
Macrophage Tropism of Human Immunodeficiency Virus Type 1 Isolates from Brain and Lymphoid Tissues Predicts Neurotropism Independent of Coreceptor Specificity
TLDR
The results suggest that HIV-1 tropism for macrophages and microglia is restricted at the entry level by a mechanism independent of coreceptor specificity, and provide evidence that M-tropism rather than CCR5 usage predicts HIV- 1 neurotropism.
HIV-1 gp120 and chemokine activation of Pyk2 and mitogen-activated protein kinases in primary macrophages mediated by calcium-dependent, pertussis toxin-insensitive chemokine receptor signaling.
TLDR
The gp120 signaling cascade in macrophages includes coreceptor binding, PTX-insensitive signal transduction, ionic signaling including Ca++ influx, and activation of Pyk2 and MAPK pathways, and leads to secretion of inflammatory mediators.

TLDR
The results demonstrate that HIV-1 variants in the CNS may possess a broader range of biological characteristics than generally appreciated, raise the possibility that X4 strains may participate in AIDS neuropathogenesis, and provide a prototype clade B HIV- 1 strain that replicates efficiently in primary macrophages through the exclusive use of CXCR4 as a coreceptor.
