To examine whether oral administration of proteoglycan derived from Phellinus linteus, which is known as the medicinal mushroom, can prevent or treat collagen-induced arthritis (CIA) in mice as experimental model of autoimmune disease. CIA was induced by intradermal injection of type II collagen (CII) emulsified with complete freund's adjuvant (CFA) into the base of the tail (on day 7) followed...

Background. Wutou decoction (WTD) has been wildly applied in the treatment of rheumatoid arthritis and experimental arthritis in rats for many years. Epigenetic deregulation is associated with the aetiology of rheumatoid arthritis; however, the effects of WTD on epigenetic changes are unclear. This study is set to explore the effects of WTD on DNA methylation and histone modifications in rats w...

BACKGROUND & OBJECTIVES The extracts from Caltha palustris L. have been shown to be beneficial for treating arthritis and rheumatism. In this study, the immunomodulatory effects of polysaccharide fractions B and C of C. palustris extracts were studied, using the collagen-induced arthritis (CIA) mouse arthritis experimental model. The aim was to determine the activity of blood phagocytic cells a...

BACKGROUND Bombina variegate peptide 8 (Bv8) is a small protein secreted by frog skin. Recently it has been shown to contribute to tumor angiogenesis in mouse model. The purpose of this study was to investigate Bv8 in mice with type II collagen-induced arthritis (CIA). METHODS We induced CIA in male DBA/1J mice. The severity of arthritis was evaluated based on an arthritis score. RNA was extr...

OBJECTIVE To investigate the mode of action of methotrexate (MTX) in different types of models for rheumatoid arthritis (RA) and multiple sclerosis (MS). METHODS Models for RA and MS were selected known to have different pathogenesis--that is, fibroblast induced arthritis in SCID mice, collagen induced arthritis (CIA), anticollagen II antibody induced arthritis (CAIA), and experimental autoim...

Distinct Notch ligands possess a characteristic ability in terms of functional T cell differentiation. However, the precise role or the therapeutic potential of each Notch ligand in autoimmune diseases is largely unknown. In this study, we examined whether Jagged1 modulates a collagen-induced rheumatoid arthritis (CIA) model by altering T cell responses. The injection of a soluble Jagged1-encod...

We have previously reported that ES-62, a molecule secreted by the parasitic filarial nematode Acanthocheilonema viteae, protects mice from developing collagen-induced arthritis (CIA). Together with increasing evidence that worm infection may protect against autoimmune conditions, this raises the possibility that ES-62 may have therapeutic potential in rheumatoid arthritis and hence, it is impo...

The gamma ray interaction depth in 3-D position scnsitive CdZnTe dctectors is currently determined by the pulse height ratio ofthe cathode signal to the anode pixel signal (CIA ratio). In expcriments with our 3-D CdZnTe dctectors, thc photopeak area as a fuuction of the CIA ratio deviates from the expected exponential attcnuation with depth. This indicatcs that the CIA ratio is not proportional...
