OBJECTIVE The expression of autoimmunity in mice deficient in programmed death 1 (PD-1) suggests that PD-1 is a candidate gene involved in the development of human autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). We therefore tested the potential association between PD-1 and the development of SLE and RA by(More)
BACKGROUND Penicillium citrinum and Aspergillus fumigatus are prevalent indoor airborne fungal species that have been implicated in human respiratory allergic disorders. It is important to understand the allergenic profile of these fungal species. The purpose of the present study is to characterize a newly identified enolase allergen from P. citrinum and A.(More)
It is believed that probiotics play an important role for the health of the host, including modulation of immune responses. Most studies have focused on the immunomodulatory effects of viable cells of lactic acid bacteria; however, we investigated those of heat-killed cells of lactic acid bacteria in this study. We first observed the effects on immune(More)
Non-proteolytic group 2 allergen, Der p 2 (DP2) is known as a major allergen derived from house dust mite Dermatophagoides pteronyssinus.Paracellular epithelial barrier, being composed of a number of tight junction (TJ) molecules, plays pivotal roles in resistance of pathogen invading. However, whether DP2 affects epithelial TJ molecules is unclear.(More)
Phenylarsine oxide (PAO), a trivalent arsenical compound, stimulated [Ca2+]i elevation in rat neutrophils in a Ca2+-containing medium but caused no appreciable response in a Ca2+-free medium. PAO also induced external Mn2+ entry, which was inhibited by N-acetyl-L-cysteine (NAC), but failed to elicit any appreciable Ba2+ and Sr2+ entry. Pretreatment of(More)
BACKGROUND Local nasal immunotherapy (LNIT) is an effective immunotherapeutic modality, especially when targeting a single immunodominant peptide from an allergen. However, the working mechanisms of LNIT are poorly understood. We hypothesized that LNIT with a mixture of group 2 allergens of Dermatophagoides pteronyssinus (Der p 2) protein and fungal(More)
In order to test the hypothesis that stratification of Mexican Modification of the Systemic Lupus Erythematosus Disease Activity Index (MEX-SLEDAI) simplifies the genetic study of SLE, we evaluated the genetic susceptibility to inflammation and defects in clearance of immune complexes among SLE patients in Taiwan. SLE phenotypes were stratified according to(More)
BACKGROUND Local nasal immunotherapy (LNIT) is an effective immunotherapy. Peptides derived from the group 2 allergen of Dermatophagoides pteronyssinus, Dp2 28-40 and Dp2 28-40A, and fungal immunomodulatory peptide (FIP) have been shown to act as T(H)1 potential and response-inducing adjuvant. LNIT by the use of Dp2 peptides in conjunction with FIP were(More)
BACKGROUND Blomia tropicalis has been reported to be a clinically important allergen in house dust. High prevalence of sensitization to B. tropicalis has been noted in asthmatic patients in Taiwan; however, the allergenic components and its impact on asthmatic patients remain to be clarified. OBJECTIVE To analyze the prevalence of IgE against B.(More)
PURPOSE Myeloid differentiation-2 (MD-2) has been associated with endotoxin and inflammatory disorders because it can recognize lipopolysaccharide (LPS) binding and attenuate Toll-like receptor 4 (TLR4)-mediated signaling. However, its role in allergic inflammation has yet to be clarified. We examined whether single nucleotide polymorphisms (SNPs) in MD-2(More)
