Abstract
Influenza A viruses cause severe respiratory illnesses in humans and animals. Overreaction of the innate immune response to influenza virus infection results in hypercytokinemia, which is responsible for mortality and morbidity. However, the mechanism by which influenza induces hypercytokinemia is not fully understood. In this study, we established a mouse-adapted H9N2 virus, MA01, to evaluate the innate immune response to influenza in the lung. MA01 infection caused high levels of cytokine release, enhanced pulmonary injury in mice, and upregulated CD83 protein in dendritic cells and macrophages in the lung. Influenza virus neuraminidase (NA) unmasked CD83 protein and contributed to high cytokine levels. Furthermore, we provide evidence that CD83 is a sialylated glycoprotein. Neuraminidase treatment enhanced lipopolysaccharide (LPS)-stimulated NF-κB activation in RAW264.7 cells. Anti-CD83 treatment alleviated influenza virus-induced lung injury in mice. Our study indicates that influenza virus neuraminidase modulates CD83 status and contributes to the "cytokine storm," which may suggest a new approach to curb this immune injury.IMPORTANCE The massive release of circulating mediators of inflammation is responsible for lung injury during influenza A virus infection. This phenomenon is referred to as the "cytokine storm." However, the mechanism by which influenza induces the cytokine storm is not fully understood. In this study, we have shown that neuraminidase unmasked CD83 protein in the lung and contributed to high cytokine levels. Anti-CD83 treatment could diminish immune damage to lung tissue. The NA-CD83 axis may represent a target for an interruption of influenza-induced lung damage.

Abstract
We have sought an endogenous membrane bound sialidase acting at neutral pH in immune system, because the removal of sialic acid from cell surfaces will affect the cell-cell interaction directly or indirectly. The levels of activity of unique membrane-bound sialidase at neutral pH and also soluble sialidase are high in the thymus but low in the spleen and lymph nodes. These are thought to be plasma membrane and cytosolic types based on the behavior of inhibition by Cu(2+) and 2-deoxy-2, 3-dehydro-N-acetylneuraminic acid. Newly synthesized 5-bromo-4-chloro-3-indolyl-N-acetylnueraminic acid was used for histochemical staining of sialidase-positive thymic cells, and the results showed positive cells sparsely distributed in the corticomedullar region or medullary region of the thymus. They expressed immunoglobulin and Mac-1 antigen on their surfaces. These cells must therefore be of a B cell lineage, not a T cell lineage. We also found that some vessels in the thymus were sialidase-positive.

Abstract
The developing immune response in the lymph nodes of mice infected with influenza virus has both Th1- and Th2-type characteristics. Modulation of the interactions between antigen-presenting cells and T cells is one mechanism that may alter the quality of the immune response. We have previously shown that the ability of dendritic cells (DC) to stimulate the proliferation of alloreactive T cells is changed by influenza virus due to viral neuraminidase (NA) activity. Here we show that DC infected with influenza virus A/PR/8/34 (PR8) stimulate T cells to produce different types of cytokines in a dose-dependent manner. Optimal amounts of the Th1-type cytokines interleukin-2 (IL-2) and gamma interferon (IFN-gamma) were produced from T cells stimulated by DC infected with low doses of PR8, while the Th2-type cytokines IL-4 and IL-10 were produced only in response to DC infected with high doses of PR8. IL-2 and IFN-gamma levels corresponded with T-cell proliferation and were dependent on the activity of viral NA on the DC surface. In contrast, IL-4 secretion required the treatment of T cells with NA. Since viral particles were released only from DC that are infected with high doses of PR8, our results suggest that viral NA on newly formed virus particles desialylates T-cell surface molecules to facilitate a Th2-type response. These results suggest that the activity of NA may contribute to the mixed Th-type response observed during influenza virus infection.

Abstract
Neuraminidase (NA) is an enzyme produced by several microorganisms, which is capable of liberating sialic acid from glycoproteins and modifying cellular adhesion mechanisms. NA is considered a virulence factor in some bacterial species and has been implicated in the pathogenesis of acute poststreptococcal glomerulonephritis, a disease in which glomerular leukocyte infiltration is a prominent feature. We examined the effect of NA on kidney infiltration by neutrophils (PMN), T lymphocytes (TL) and monocyte-macrophages (MM). Intravenous injection of NA resulted in an early increase in the number of PMN (1 hr, 3.42 +/- 0.19 cells/cgs, mean +/- SEM; 3 hr, 3.63 +/- 0.13; 6 hr, 2.9 +/- 0.24; controls, 1.53 +/- 0.18; P < 0.001) and MM (1 hr, 3.49 +/- 0.16; 3 hr, 4.02 +/- 0.2; 6 hr, 3.88 +/- 0.27; controls 1.43 +/- 0.14; P < 0.001) in the glomeruli, while TL increased later (24 hr, 2.29 +/- 0.14; 48 hr, 2.4 +/- 0.2; 72 hr, 2.16 +/- 0.15; controls 0.7 +/- 0.07; P < 0.001). PMN and TL were also increased in the interstitium (up to ninefold for PMN and up to threefold for TL). Following i.v. injection of 51Cr-labeled NA-treated leukocytes, renal radioactive uptake was significantly increased at all times tested (percent radioactivity/gram of tissue after PMN injection, 3 hr, 5.57 +/- 0.46, mean +/- SEM; 12 hr, 5.38 +/- 0.77; 60 hr, 6.51 +/- 1.1; controls, 1.26 +/- 0.17, 1.75 +/- 0.25, and 2.46 +/- 0.08, respectively; P < 0.001 in each case.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
1. The sialidase activity of human thymocyte was examined by a fluorogenic assay. 2. These studies revealed that human thymocyte sialidase activity is essentially acid-active and membrane-bound since 59.6% and 33% of the total activity was recovered in the lysosome-enriched and microsomal fractions, respectively. 3. A weak activity was also detected in the cytosolic fraction. 4. However, the acidic optimum pH of this soluble sialidase was at variance with the general concept of mammalian soluble sialidases which are known to be optimally active at more neutral pH. 5. This acidic soluble sialidase seems to be a general characteristic of the human T-cell lineage since examination of mature circulating T-cells revealed that they contain a soluble sialidase activity similar to that observed in thymocytes. 6. Analysis of mature and immature thymocyte subpopulation obtained by differential PNA agglutination indicated that this enzymatic system was not altered during the course of thymic maturation. 7. These results suggest that unlike in T-cell activation where changes in the level of sialidase activity were shown to influence the extent of cell surface sialylation and thereby the cell physiology, this enzymatic system seems not to be involved in the fluctuation of cell surface sialic acid content observed during thymic maturation.

Abstract
To investigate the mechanism of spontaneous attachment of afferent lymph lymphocytes to dendritic cells, cells from canine skin lymph were used. There were 3.3 +/- 2.8% of veiled cells in clusters found in lymph flowing from the cannulated lymph vessel. The number of clusters forming ex vivo in the collected lymph samples increased as a function of time and was temperature dependent. Incubation of cells with proteolytic enzymes or monosaccharides did not alter cell interactions. The ability of veiled cells to bind lymphocytes was independent of divalent cations but reduced by xylocaine and retinoic acid. Among steroids only methylprednisolone showed an inhibitory effect on cluster formation. Indomethacin and acetylsalicylic acid had no blocking activity on cell binding. Also, no effect was seen after treatment with cyclosporine A and azathioprine. An enhanced cluster formation after desialation with neuraminidase was observed. The desialated cells were cultured in order to study their stimulatory and accessory cell functions. No enhancement of autologous mixed leucocyte reaction was seen, but a significantly higher responsiveness to a suboptimal dose of phytohaemagglutinin was observed. The N-ase-mediated non-specific cell attachment could be abrogated by cell washing or treatment with EDTA or xylocaine. This study indicates that cluster formation by skin lymph veiled cells and lymphocytes is a spontaneous process which cannot be controlled by means usually effective in regulating the in vitro induced clustering of antigen-stimulated cells.

Abstract
The potential of cells within the central nervous system (CNS) to initiate T lymphocyte responses is not known and was the subject of this study. Using the ability of virgin T lymphocytes to proliferate in a primary response to allogeneic determinants on antigen-presenting cells (APC), we have examined the capacity of major histocompatibility complex (MHC)-expressing astroglial cells to act as stimulators of primary and secondary T cell responses. Neither freshly isolated astrocytes nor primary astrocyte cultures pretreated with interferon gamma (IFN-gamma) to upregulate MHC class I and II expression stimulated unfractionated lymph node (LN) cell populations in the primary mixed lymphocyte reaction. In mixing experiments, astrocytes did not inhibit the T cell response to allogeneic LN stimulators. Purified responder CD4+ T cells also were not stimulated to proliferate or secrete interleukin 2 (IL-2) by MHC class I- and II-expressing astrocytes. In contrast to their inability to stimulate virgin, alloreactive CD4+ T cells, astrocytes were able to specifically stimulate an alloreactive CD4+ T cell line. Unprimed CD8+ T cells, however, exhibited some weak autonomous proliferation to astrocyte stimulators but this response was only substantial in the presence of exogenous IL-2, the latter predominantly being a CD4+ T cell product. Those CD8+ T cells responding in the presence of IL-2 were mainly T cell receptor alpha/beta+ IL-2 receptor (alpha chain)+, and a majority had shifted from high to low CD45R expression. Given the virtual dependence of CD8+ T cells in these studies, on CD4+ T cell help, and the complete absence of activation of this latter subset by astrocytes, it is clear that in the context of this resident CNS cell, further activation of either T cell subset by astrocytes within the CNS can only follow priming by another type of APC. The implications of these results for the induction of T cell responses in the CNS are discussed.

Abstract
Dendritic cells (DCs), such as Langerhans cells (LCs) of the epidermis and the DCs of lymphoid organs such as spleen, are potent antigen presenting cells. DCs express high levels of major histocompatibility complex (MHC) class II molecules, but, partly because of the low numbers of primary DCs in any tissue, there has been no detailed study of the biochemistry of their class II molecules. This information may be needed to help explain recent findings that DCs process native protein antigens when freshly isolated from epidermis and spleen. Processing ceases during culture, yet a strong accessory function for activating resting T cells develops. We studied immunoprecipitates of DC class II and invariant chain (Ii) molecules by two-dimensional gel electrophoresis. We found that (i) freshly isolated LCs synthesize large amounts of class II and Ii polypeptides; (ii) Ii molecules that are known to be involved in antigen processing display an unusually large number of sialic acids in fresh LCs; (iii) with culture, class II and Ii synthesis decreases dramatically and has virtually ceased at 3 days; and (iv) the turnover of class II in pulse/chase experiments is slow, being undetectable over a 12- to 32-hr culture period, whereas the turnover of Ii is rapid. We conclude that MHC class II molecules of DCs do not seem to be qualitatively unique. However, the regulation of class II and Ii expression is distinctive in that biosynthesis proceeds vigorously for a short period of time and the newly synthesized class II remains stably on the cell surface, whereas Ii turns over rapidly. This may enable DCs to process and retain antigens in the peripheral tissues such as skin and migrate to the lymphoid organs to activate T cells there.

Abstract
There is now considerable evidence, from in vivo and in vitro studies, supporting the claim that dendritic cells are the principal accessory cells of the vertebrate immune system. Until recently, however, the biology of the dendritic cell accessory mechanism has remained obscure. Here, Philip King and David Katz review recent findings that have clarified several aspects of this mechanism, providing a possible basis for the potent T-cell stimulating capacity of the dendritic cell, and yielding clues to the ontogenetic relationships of these cells and to their role in immunopathology.

Abstract
The B6 anti-bm6 allospecific CTL response is strictly dependent on CD4+ cells when using LPS blasts as stimulator cells. Altering the N-linked carbohydrates on stimulator cells by use of the N-linked trimming glycosidase inhibitors 1-deoxymannojirimycin and swainsonine, or by treatment with bacterial neuraminidase, results in a restoration of the B6 anti-bm6 response in the absence of CD4+ cells. The extent of restoration is inversely correlated with the number of sialic acids present on N-linked glycans of stimulator cells.

Abstract
In this study, we have shown that human tonsillar T cells adhere to phorbol 12-myristate 13-acetate(PMA)-differentiated U-937 cells. To examine the molecular mechanisms involved, the effect of a panel of monoclonal antibodies upon this adhesion was assessed in a quantitative binding assay. Antibodies against LFA-1 and ICAM-1 inhibited binding, directly implicated these molecules in T cell-PMA-induced U-937 adhesion. Furthermore, the adhesion was magnesium but not calcium dependent. Of the remaining antibodies that were tested, none of those against CD2, LFA-3, Mac-1, p150,95, CD43, CD45RA or CD56 affected binding. However, antibodies against CD44, CD45, CD45RO, CD46 and CD55 enhanced binding suggesting an anti-adhesive role for these molecules during U-937-T cell interaction.

Abstract
The effect of influenza virus infection on the expression of major histocompatibility complex (MHC) antigens was investigated. Infection with influenza virus resulted in an increase of the binding of anti-MHC class I and class II antibodies to resting T cells. The binding of anti-MHC class II antibodies to activated T cells was increased approximately threefold. The binding of anti-MHC class I and class II antibodies to Epstein-Barr virus-transformed B cells appeared unaffected after influenza virus infection. Recombinant human interferon-alpha and/or -gamma added to T cells did not enhance the binding of anti-MHC antibodies. Biochemical analysis revealed no increase in the amount of class I and class II antigens as a consequence of viral infection, but a marked decrease in sialic acid content was found, most probably caused by the viral neuraminidase. Pulse-chase experiments suggest that the viral neuraminidase can catalyze the removal of sialic acids both en route to and at the cell surface. The absence of sialic acid residues can explain the increased binding of anti-MHC antibodies, because neuraminidase (clostridium perfringens) treatment of T and Epstein-Barr virus-transformed B cells resulted in a shift in both isoelectric point and antibody binding similar to that observed after influenza virus infection.
