Recent studies regarding developmental changes in the myocardial contractile system from fetal, newborn, and adult animals are reviewed. From the data obtained so far, we conclude that in the early fetus myocardial contraction is mainly dependent on Ca which enters via the sarcolemma. Ca release from the sarcoplasmic reticulum is minimal. The role of the(More)
The skin is an immune organ that contains innate and acquired immune systems and thus is able to respond to exogenous stimuli producing large amount of proinflammatory cytokines including IL-1 and IL-1 family members. The role of the epidermal IL-1 is not limited to initiation of local inflammatory responses, but also to induction of systemic inflammation.(More)
To the Editor: IL-10 is a regulatory cytokine secreted during inflammatory responses that restrains immune cell proliferation; it plays a pivotal role in the acquisition andmaintenance of antigen-specific T-cell tolerance. Peptide-based allergen-specific immunotherapy is currently being used for the treatment of several allergic diseases, and the induction(More)
Atopic dermatitis (AD) is a chronic disease with Th2-type-cytokine dominant profile. Several cytokines and related peptides had been tried for the treatment of AD but with unsuccessful results; a part of the reason is the limitation of their biological half time. We have recently developed a highly efficient mouse dominant negative IL-4/IL-13 DNA vaccine,(More)
IL-10 plays a critical role in the induction of specific T-cell tolerance. To date, whether IL-10 induction by antigen application is dose- or time-dependent remains unclear. In this study, IL-10 induction by allergen exposure was investigated in the several schedules. Oxazolone was repeatedly applied to mouse ear, and mRNA of inflammatory cytokines in(More)
Malignant melanoma (MM) is an aggressive cutaneous malignancy associated with poor prognosis; many putatively therapeutic agents have been administered, but with mostly unsuccessful results. Propionibacterium acnes (P. acnes) is an aerotolerant anaerobic gram-positive bacteria that causes acne and inflammation. After being engulfed and processed by(More)
T cells have been classified as belonging to the Th1 or Th2 subsets according to the production of defining cytokines such as IFN-γ and IL-4. The discovery of the Th17 lineage and regulatory T cells shifted the simple concept of the Th1/Th2 balance into a 4-way mechanistic pathway of local and systemic immunological activity. Clinically, the blockage of(More)
