Abstract
Purpose This study was the first to screen the active compounds of Jian Aikang Concentrated Pill (JAKCP) with network pharmacology, predict its potential targets, screen the signaling pathways, and combine with cellular experimental validation to explore the potential mechanism of JAKCP for the treatment of acquired immunodeficiency syndrome (AIDS). Methods The main compounds and targets of Chinese herbs in JAKCP were identified by TCMSP; the targets of AIDS were collected from Genecards, Online Mendelian Inheritance in Man (OMIM), Disgenet, Therapeutic Target Database (TTD) and Drugbank; the network of “Chinese herbs-active compounds-targets” for JAKCP was constructed by Cytoscape, and protein–protein interaction (PPI) network was constructed using STRING to generate the intersection targets, Metascape was conducted to analyze the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), and the network of “main active compounds-core targets-pathways” was constructed by Cytoscape. Finally, the effect of JAKCP on the survival rate of HIV pseudovirus-infected MT-4 cells was investigated by CCK-8 assay, and the predicted targets were verified by ELISA, qPCR and Western blot. Results A total of 147 active compounds of JAKCP were screened covering 351 targets and 416 AIDS disease targets were obtained, besides 140 intersection targets and 321 KEGG pathways were collected. Ultimately, quercetin, kaempferol, stigmasterol, beta-sitosterol, epigallocatechin gallate were identified as the important compounds, the core targets are HSP90AA1, IL-10, IL-6, TNF, IL-1β, TP53, and IL-1ɑ, and the biological pathways and processes mainly include T cell activation, regulation of DNA-binding transcription factor activity and apoptotic signaling pathway. Experiments on the targets of “T cell activation” demonstrated that JAKCP promotes the survival of HIV pseudovirus-infected MT-4 cells. Also, JAKCP down-regulated mRNA and protein levels of IL-1ɑ, IL-1β, and IL-6 while up-regulated mRNA and protein levels of IL-2, IL-6ST, and IL-10 in vitro. Conclusion JAKCP exerted regulatory immune functions through multi-component, multi-target and multi-pathway, thereby providing novel ideas and clues for the treatment of AIDS.

Abstract
We generated human dendritic cell (DC) hybridoma cell lines by fusing HGPRT-deficient promonocytic U937 cells with immature DCs obtained by culturing peripheral blood monocytes with interleukin-4 (IL-4; 1,000 U/ml) and granulocyte-macrophage colony-stimulating factor (100 U/ml) for 7 days and mature DCs by treatment with tumor necrosis factor alpha (12.5 microg/ml) for 3 days. Only one fusion with immature DCs was successful and yielded four cell lines--HB-1, HB-2, HB-3, and HB-9--with an overall fusion efficiency of 0.0015%. The cell lines were stable in long-term culture, displayed morphological features typical of DCs, and expressed distinct class I and class II molecules not present on U937 (A*031012, B*51011, Cw*0701, DRB3*01011 52, and DR5*01011). A representative cell line, HB-2, that expressed DC markers including CD83, CD80 and CD86 could be induced to produce IL-12 through CD40 stimulation. After human immunodeficiency virus (HIV) infection, there was impairment of antigen-presenting cell (APC) function, which was manifested by an inability to stimulate allogeneic T-cell responses. There was no change in expression of major histocompatibility complex class I and class II antigens, CD83, CD40, CD4, CD11c, CD80, CD86, CD54, and CD58, or IL-12 production in the HIV-infected HB-2 cells. The HIV-infected HB-2 cells induced T-cell apoptosis in the cocultures. T-cell proliferation could be partially restored by using ddI, indinivir, and blocking anti-gp120 and anti-IL-10 antibodies. Our data suggest that there are multiple mechanisms that DCs use to inhibit T-cell responses in HIV-infected patients. The HB-2 cell line could be a useful model system to study APC function in HIV-infected DCs.

Abstract
Leukocyte infiltrates that can serve as viral reservoirs, and sites for viral replication are found in many organs of HIV-1-infected patients. Patients whose blood leukocytes migrate across confluent endothelial monolayers ex vivo and transmit infectious virus to mononuclear leukocytes (MNLs) lodged beneath this endothelial barrier have a worse prognosis. We evaluated the ability of 110- to 120-kDa fibronectin fragments (FNf), which are found in the blood of >60% of HIV-1-infected patients, to stimulate transendothelial migration and drive productively infected MNLs into a potential perivascular space. FNf induced MNLs to release TNF-alpha in a dose-dependent fashion; the resulting increase in lymphocyte and monocyte transendothelial migration could be blocked with soluble TNF receptor I. Rather than penetrate deeply into the subendothelial matrix, as is seen with untreated controls, FNf-treated MNLs clustered just below the endothelial monolayer. Treatment with FNf during migration increased subsequent recovery of HIV-infected cells from the subendothelial compartment. FNf treatment also significantly increased the numbers of HLA-DR(bright), dendritic-type cells that reverse-migrated from the subendothelial depot to the apical endothelial surface 48 h after migration. Fibronectin fragments can be produced by viral and host proteases in the course of inflammatory conditions. The ability of FNf to stimulate transendothelial migration of HIV-1-infected MNLs may help to explain the dissemination of this infection into cardiac, renal, and CNS tissues.

Abstract
The phenotypic differentiation of systemic macrophages that have infiltrated the central nervous system, pericytes, perivascular macrophages, and the "real" resident microglial cells is a major immunocytochemical and immunohistochemical concern for all users of cultures of brain cells and brain sections. It is not only important in assessing the purity of cell cultures; it is also of fundamental importance in the assessment of the pathogenetic significance of perivascular inflammatory phenomena within the brain. The lack of a single membranous and/or biochemical marker allowing conclusive identification of these cells is still a major problem in neurobiology. This review briefly discusses the functions of these cells and catalogs a large number of membranous and biochemical markers, which can assist in the identification of these cells.

Abstract
The ability of dengue virus-infected human monocyte-derived macrophages to induce permeability changes in primary human umbilical vein endothelial cells was investigated. Supernatants from dengue virus type 2-infected monocyte-derived macrophages increased permeability in human umbilical vein endothelial cell monolayers without inducing endothelial cell infection. Production of permeabilising activity from monocyte-derived macrophages occurred after the peak of progeny virus release. TNF-alpha, a known inducer of endothelial cell permeability, was released from dengue virus infected monocyte-derived macrophages but its release did not coincide with release of endothelial cell permeabilising activity. Permeability induction was enhanced by pre-incubation with supernatants from infected monocyte-derived macrophages harvested at the time of peak release of TNF-alpha and infectious virus. Thus, supernatants from dengue virus-infected monocyte-derived macrophages contain factors that increase human umbilical vein endothelial cell permeability, but this is not accompanied by endothelial cell infection or directly correlated with release of dengue virus or TNF-alpha from monocyte-derived macrophages. This model system can be used for further in vitro analysis of mechanisms that may relate to capillary leakage and the development of dengue haemorrhagic fever/dengue shock syndrome.

Abstract
Most cases of human immunodeficiency virus (HIV) infection worldwide occur following sexual contact, implying that the virus may breach the protective epithelial barrier lining the genital tract. HIV infection is known to preferentially occur when the genital epithelial integrity is altered, particularly when epithelial micro-ulcerations occur during heterosexual intercourse or ulcerations appear, due to sexually transmitted infections or else in the context of ectopy of the endocervical mucosa, which may leave the genital tissue. We report that R5-tropic infectious HIV-1 isolates are capable of in vitro transcytosis through a tight and polarized monolayer of human endometrial HEC-1 cells. Transcytosis of HIV particles was increased 2-fold within a pro-inflammatory micro-environment. Our findings suggest that transcytosis may be a relevant mechanism for the passage of virus through the genital mucosa in vivo, particularly when inflammatory cells and mediators are present in the vicinity of the mucosal surface.

Abstract
Experiments on the host cell spectrum of bovine leukaemia virus (BLV), a retrovirus closely related to the human T-cell leukaemia virus (HTLV), have yielded conflicting data. Currently, BLV is known to infect B cells, whereas its ability to infect other cell types, e.g. monocytes/macrophages, is doubtful. As monocytes/macrophages may have profound effects on the diversity of the T-cell response, we studied the possibility of in vitro infection, using bovine monocytes and SV40-transformed bovine macrophages. Proviral DNA was detected by nested polymerase chain reaction (PCR) from day 1 until the end of the experiments at either day 5 or day 80, depending on the quantity of virus used for infection. In addition, the infection was associated with morphological changes in infected cells as revealed by electron microscopy. The in vitro infection did not significantly change either the expression of surface antigens (CD11b, CD32, and major histocompatibility complex (MHC) class II) or the amounts of cytokine transcripts (interleukin (IL)-1beta, tumour necrosis factor (TNF)-alpha, IL-6 and IL-12p40) with or without lipopolysaccharide (LPS) stimulation. The data suggest that BLV can infect monocytes, but the infection does not seem to influence the function or the phenotype of these cells. Infected monocytes may, however, play a role as a viral reservoir in vivo.

Abstract
Interleukin-16 (IL-16) acts as a chemoattractant for CD4+ cells, as a modulator of T-cell activation, and plays a key role in asthma. This report describes the cytokine-inducing effects of IL-16 on total peripheral blood mononuclear cells (PBMC) and PBMC subpopulations. While CD4+ T lymphocytes did not secrete cytokines in response to rhIL-16, CD14+ CD4+ monocytes and maturing macrophages secrete IL-1beta, IL-6, IL-15 and tumour necrosis factor-alpha (TNF-alpha) upon rhIL-16 stimulation. The mRNA species for these four cytokines were detected as early as 4 hr post-stimulation, with protein being secreted by 24 hr. Secretion of IL-1beta and IL-6 by total PBMC was dose dependent, with maximal secretion being observed using 50 ng/ml rhIL-16. However, for IL-15 or TNF-alpha maximal secretion by total PBMC occurred with all concentrations between 5 ng/ml to 500 ng/ml rhIL-16. Purified monocytes/macrophages secreted maximal concentrations of all four cytokines in the presence of 500 ng/ml rhIL-16, except for monocytes where maximal secretion of IL-15 was, interestingly, observed with only 50 ng/ml rhIL-16. The use of higher concentrations of rhIL-16 (1000 ng/ml) inhibited secretion of all four cytokines. While these IL-16-induced cytokines are likely to be involved in the immune system's response to antigen, the data suggest that IL-16 may play a key role in initiating and/or sustaining an inflammatory response.

Abstract
We investigated whether culture conditions could affect the RANTES antiviral effect on human immunodeficiency virus type 1 (HIV-1) infection of primary macrophages. Monocyte-derived macrophages (MDM) were obtained either as (1) the adherent cells of 5-day cultures of blood mononuclear cells (PBMC), followed by 2 days without nonadherent PBMC or added cytokines (MDM-5d), or (2) as the adherent cells recovered from 1-h incubation of PBMC, which were cultured for 7 days with macrophage colony-stimulating factor (M-CSF; MDM-MCSF). Infection of MDM-5d from different donors with HIV-1 R5 strains was reproducibly inhibited by RANTES (IC50 < or = 10 nM), but infection of MDM-MCSF was not inhibited by > or = 100 nM RANTES, even when added at initiation of cultures, although it was still inhibited by a CD4 antibody. RANTES had no antiviral effect when MDM-5d were treated with physiological concentrations of M-CSF or GM-CSF before infection. CCR5 and CXCR4 expression as well as that of other cell surface molecules, including adhesion molecules, was not affected by the cytokines. MDM-MCSF from delta 32CCR5 homozygous individuals did not render them permissive to HIV-1, suggesting that it is unlikely that the virus uses another coreceptor. RANTES binding to MDM was chondroitin sulfate, but not heparan sulfate, dependent, and RANTES bound more efficiently to MDM-5d than to MDM-MCSF. Chondroitin sulfate removal partially offset the RANTES antiviral effect for MDM-5d. Thus RANTES anti-HIV-1 activity for primary macrophages depends on culture conditions and their consequent activation status, which may lead to differences in proteoglycan surface expression. These data may be relevant for the development of chemokine-based therapy for HIV-1 infection.
