Abstract
Dendritic cells (DCs) are the most specialized APCs that play a critical role in driving Th2 differentiation, but the mechanism is not fully understood. Here we show that vacuolar protein sorting 33B (Vps33B) plays an important role in this process. Mice with Vps33b-specific deletion in DCs, but not in macrophages or T cells, were more susceptible to Th2-mediated allergic lung inflammation than wild-type mice. Deletion of Vps33B in DCs led to enhanced CD4+ T cell proliferation and Th2 differentiation. Moreover, Vps33B specifically restrained reactive oxygen species production in conventional DC1s to inhibit Th2 responses in vitro, whereas Vps33B in monocyte-derived DCs and conventional DC2s was dispensable for Th2 development in asthma pathogenesis. Taken together, our results identify Vps33B as an important molecule that mediates the cross-talk between DCs and CD4+ T cells to further regulate allergic asthma pathogenesis.

Blocking B7-1/CD28 Pathway Diminished Long-Range Brain Damage by Regulating the Immune and Inflammatory Responses in a Mouse Model of Intracerebral Hemorrhage. Neurochem Res 2016; 41:1673-83. [PMID: 26980009 DOI: 10.1007/s11064-016-1883-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Revised: 02/28/2016] [Accepted: 03/02/2016] [Indexed: 01/21/2023]
Abstract
Acute brain injuries can activate bidirectional crosstalk between the injured brain and the immune system. The immune system, particularly T lymphocytes and cytokines, has been implicated in the progression of brain injury after intracerebral hemorrhage (ICH). Co-stimulatory molecules B7-1 (CD80)/B7-2 (CD86) binding cognate receptor provides a secondary signaling to T cell activation. The aim of our study was to explore the effects of anti-B7-1 antibody on the development and prognosis of cerebral hemorrhage and to investigate the possible underlying mechanism. Mice were inner canthus veniplex administered with anti-B7-1 antibody at 10 min and 24 h after ICH and sacrificed on the third day after ICH. Immune function was assessed via splenocyte proliferation assay and organism index, respectively. IFN-γ and IL-4 were detected by enzyme-linked immuno sorbent assay. The cerebral edema was evaluated via brain water content. The levels of autophagy and apoptosis related proteins were measured by western blotting analysis. In addition, functional outcome was studied with pole-climbing test and morris water maze. The mice were weighed on 0, 1, 3, 14 and 21 days after ICH. The treatment with anti-B7-1 antibody significantly lowered immune function, and reduced the latency of water maze on 18 and 20 days, the ratio of IFN-γ/IL-4 as well as body weight on day 3 after cerebral hemorrhage. Our study suggests that in the cerebral hemorrhage mice brain anti-B7-1 antibody may reduce long-range brain damage by reversing immune imbalance.

Ann Allergy Asthma Immunol 2013; 111:276-81. [PMID: 24054363 DOI: 10.1016/j.anai.2013.06.030] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2013] [Revised: 06/18/2013] [Accepted: 06/20/2013] [Indexed: 11/17/2022]
Abstract
BACKGROUND B7 molecules play a key role in regulating allergen-induced T cell activation in asthma, which may occur through T cell recruitment and T helper cell differentiation on allergen provocation. Initial studies have shown that B7-H3 (CD276), a recently identified B7 family member, plays a critical role in the development of Th2 cells. OBJECTIVE To investigate the effects of anti-B7-H3 monoclonal antibody (mAb) in a mouse model of allergic asthma. METHODS The asthma model was established by ovalbumin (OVA) sensitization and challenging in female BALB/c mice. Total cell numbers in bronchoalveolar lavage fluid (BALF) were determined, and the expression levels of interferon gamma (IFN-γ), interleukin (IL)-4, and IL-17 in BALF were measured by enzyme-linked immunosorbent assay. Pulmonary eosinophil infiltration and mucus production were detected by hematoxylin and eosin (H&E) and periodic acid-Schiff (PAS), respectively. B7-H3 expression was detected by immunohistochemistry in frozen tissue sections. RESULTS Anti-B7-H3 mAb treatment alleviated the asthmatic syndrome, decreased the levels of B7-H3-positive cells in the lung tissues, abrogated hypercellularity, eosinophil infiltration, and mucus production, and inhibited IL-4 and IL-17 production in BALF at the induction phase as compared with the immunoglobulin G (IgG) control group (P < .01). In addition, the treatment of anti-B7-H3 mAb at the induction phase could increase the expression levels of IFN-γ as compared with the IgG control group (P < .01). Anti-B7-H3 mAb treatment at the effector phase did not inhibit the asthma response. CONCLUSION Blockade of B7-H3 signals may provide a novel therapeutic approach to the treatment of allergic asthma.

Int J Pharm 2013; 450:21-30. [PMID: 23608202 DOI: 10.1016/j.ijpharm.2013.04.023] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2012] [Revised: 02/24/2013] [Accepted: 04/08/2013] [Indexed: 10/26/2022]
Abstract
Severe adverse events have been frequently associated with taking the commercially available formulation of α-asarone injection (α-asarone-I). Hence, we sought to develop an intravenous lipid emulsion of α-asarone (α-asarone-LE), where we hypothesized that these adverse events could be prevented. Using a central composite design-response surface methodology, we developed and optimized an emulsion formulation of α-asarone-LE that composed of 10.0% (w/v) soybean oil, 0.4% (w/v) α-asarone, 1.2% (w/v) soybean lecithin, 0.3% (w/v) F68, and 2.2% (w/v) glycerol. The mean particle size of α-asarone-LE was 226±11 nm, the ζ-potential was -25.6±1.2 mV, the encapsulation efficiency was 99.2±0.1% and the drug loading efficiency was 3.45%. Stability, safety, and efficacy studies of α-asarone-LE were systematically investigated and compared to those of α-asarone-I. The α-asarone-LE not only showed a desired stability, but also exhibited excellent safety and improved efficacy in vivo, indicating its great potential for clinical application in the future.

Abstract
BACKGROUND Allergic asthma is a T(H)2-promoted hyperreactivity with an immediate, IgE, and mast cell-dependent response followed by eosinophil-dominated inflammation and airway obstruction. OBJECTIVE Because costimulation by CD28 is essential for T(H)2 but not T(H)1 responses, we investigated the effect of selective interference with this pathway in mice using the models of ovalbumin and house dust mite-induced airway inflammation. METHODS To study the role of CD28 in the effector phase of allergic airway inflammation, we developed an inducibly CD28-deleting mouse strain or alternatively used a CD28 ligand-binding site-specific mouse anti-mouse mAb blocking CD28 engagement. RESULTS We show that even after systemic sensitization to the allergen, interruption of CD28-mediated costimulation is highly effective in preventing airway inflammation during challenge. In addition to improving airway resistance and histopathologic presentation and reducing inflammatory infiltrates, antibody treatment during allergen challenge resulted in a marked relative increase in regulatory T-cell numbers among the CD4 T-cell subset of the challenged lung. CONCLUSION Selective interference with CD28-mediated costimulation during allergen exposure might be an attractive therapeutic concept for allergic asthma.

Abstract
We studied possible involvement of ATP in the influence of protein sensitization on contractile function and non-quantum secretion in the end-plate of isolated skeletal muscles from mouse leg. The dynamic vector of muscle contraction force was shown to correlate with changes in non-quantum secretion of acetylcholine under various conditions of experimental pathology. However, the degree of these changes was lower in sensitized animals. It can be hypothesized that the ATP-induced variability in functional properties of slow muscles during protein sensitization reflects the development of resistance to external loads. The adaptive changes in fast muscles during protein sensitization are not associated with the ATP-mediated mechanisms of excitation.

Abstract
A transdermal drug delivery system has been reported that can increase the bioavailability, reduce the administration duration, and maintain the concentration of drug in blood. In the present study, drug-in-adhesive transdermal patches of α-asarone using Eudragit E100 as pressure-sensitive adhesives and oleic acid plus isopropyl myristate as penetration co-enhancers were developed. In vitro permeation, in vivo pharmacokinetics in rabbits, and efficacy in asthmatic rats were evaluated. The results showed that co-enhancers could induce a synergistic effect on α-asarone permeability. In vivo study suggested that the patch can keep a relatively certain blood level of drug within 10-30 h in rabbits. Furthermore, the patch with the size of 4 cm² containing drug 3 mg/cm² showed a noticeable treating effect on asthmatic rats which is equivalent to the effect of dexamethasone, while avoiding the side-effect induced by the corticorsteroid. This suggests that the drug-in-adhesive transdermal patch is a promising delivery system containing α-asarone to be used for asthma treatment.
