Chronic obstructive pulmonary disease (COPD) is a systemic inflammatory disorder. It often causes weight loss, which considered poor prognostic factor. A Japanese herbal Kampo medicine, Hochuekkito (TJ-41), has been reported to prevent inflammation and loss in COPD patients, but the underlying biological mechanisms remain unknown. In present study, we investigated role of TJ-41 vivo using mouse...

The role of neoantigens in generating T cell responses that control cutaneous squamous carcinoma (cSCC) is unknown. To investigate this, solar UV-induced invasive cSCC tumors were used to create clonal lines on the BALB/c background. These constitutively express MHC class I, and thus, can be targeted for destruction by CD8 cells. Intradermal injection these cells reliably forms wild-type mice. ...

background the imbalance in the t helper (th) 1/th2 and th1/t regulatory (treg) cells-related immune responses plays a key role in pathogenesis of allergic asthma. objectives the aim of this study was to evaluate the effects of cpg-oligodeoxynucleotide (cpg-odn), monophosphoryl lipid a (mpla) and bacillus calmette-guerin (bcg) on the ratio of th1/th2 and th1/treg cells-related parameters in an ...

the purpose of the current study was to evaluate the anti-inflammatory activity of tetramethlpyrazine on oxazolone-induced colitis mice. spleen mononuclear cells (smc), lamina propria mononuclear cells (lpmc) and peripheral blood mononuclear cells (pbmc) were isolated from oxazolone-induced colitis and normal mice. the colitis cells treated by oxazolone were randomly divided into model, low dos...

Contact hypersensitivity (CHS) mouse model induced by 2, 4-dinitrofluorobenzene (DNFB) is thought to be a T helper 1 (Th1)-dominant response and used for investigating anti-inflammatory and immunosuppressive agents. However, it is hardly used for screening large-scale drugs because of the large number of animals and complex mechanisms involved in-vivo. In this study, we focused on whether T lym...

objective(s):development of new generation of vaccines against leishmaniasis is possible because long-term protection is usually seen after recovery from cutaneous leishmaniasis. iscomatrix is particulate antigen delivery system composed of antigen, cholesterol, phospholipid and saponin. in this study, the role of iscomatrix bilayer composition made by different phase transition temperature (tc...

Vicia genus has 45 species in Iran. Many protective and biological activities have been reported from these species.  In spite of many works, nothing is known about protective effect of V. cracca against hypoxia conditions. In this study, protective effects of V. cracca extract against hypoxia-induced lethality in mice were evaluated by three experimental models of hypoxia, asphyctic, haem...

Objective(s)CpG oligodeoxynucleotides (CpG ODNs) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. Due to susceptibility of phosphodiester CpG ODNs (PO CpG) to nuclease degradation, nuclease-resistant phosphorothioate CpG ODNs (PS CpG) were currently utilized in an in vivo model. In this study, according to some recently reported drawbacks with PS ...

Background and Objective: Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's disease that affects 3% of the population. PD involves a progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc) and subsequent loss of dopamine. Dopamine depletion leads to movement dysfunction and is accompanied with tremor, rigid muscle...
