Clin Exp Allergy . 2012 Aug; 42(6):946-57. PMID: 22909166
Background: Oral tolerance is a classically used strategy for antigen-specific systemic immunotherapy. However, the roles of IL-17 in modification of oral tolerance are not yet understood. Objective: To define the...

Clin Exp Allergy . 2009 Dec; 40(2):317-26. PMID: 20015276
Background: ONO-1301 is a novel drug that acts as a prostacyclin agonist with thromboxane A(2) (TxA(2)) synthase inhibitory activity. We investigated the effect of ONO-1301 on development of airway allergic...

Hara K, Hasegawa T, Ooi H, Koya T, Tanabe Y, Tsukada H, et al.
Lung . 2001 Aug; 179(1):9-20. PMID: 11479690
Eosinophilic bronchitis is an essential component of bronchial asthma, and eosinophils play an important role. We studied the effect of eosinophils on cell surface plasmin generation by bronchial epithelial cells,...

Eur J Haematol . 1999 Dec; 63(5):306-12. PMID: 10580562
In humans, the numbers of erythrocytes and granulocytes, but not that of lymphocytes, tend to increase in parallel. To determine the mechanism, we investigated how the administration of erythropoietin induces...

Koya T, Honda S, Narita J, Watanabe H, Arakawa M, Abo T
Immunology . 1999 May; 96(3):447-56. PMID: 10233727
The appendix as well as the small intestine have recently been found to carry c-kit+ stem cells which give rise to extrathymic T cells. In this study, the properties of...

Honda S, Nemoto K, Mae T, Kinjoh K, KYOGOKU M, Kawamura H, et al.
Clin Exp Immunol . 1999 Apr; 116(1):153-63. PMID: 10209520
Both MRL-lpr/lpr (lpr) and BXSB mice fall victim to autoimmune disease as a function of age. To combine their properties, brother-sister mating of (female lpr x male BXSB)F1 mice was...

Cell Immunol . 1999 Mar; 192(2):149-58. PMID: 10087183
It is known that ALY/Nsc Jcl-aly/aly (aly/aly) mice that congenitally lack lymph nodes fall victim to Sjögren syndrome as a function of age. We investigated how TCRint cells of extrathymic...

Musha N, Yoshida Y, Sugahara S, Yamagiwa S, Koya T, Watanabe H, et al.
Clin Exp Immunol . 1998 Aug; 113(2):220-8. PMID: 9717971
A particular T cell population expressing NK cell markers, CD56 and CD57, exists in humans. Many CD56+ T and CD57+ T cells (i.e. NK T cells) exist in the liver...

Cell Immunol . 1997 May; 177(2):144-53. PMID: 9178641
Granulocytes and extrathymic T cells are often activated simultaneously, but they are absolutely separate populations in normal mice. However, some abnormal extrathymic T cells (i.e., CD3int cells) seen in mice...
