  • The leukocyte adhesion to endothelium is pivotal in leukocyte recruitment which takes place during inflammatory, autoimmune and infectious conditions. The interaction between leukocytes and endothelium requires an array of adhesion molecules expressed on leukocytes and endothelial cells, thereby promoting leukocyte recruitment into sites of inflammation and tissue injury. Intervention with the adhesion molecules provides a platform for development of anti-inflammatory therapeutics. This review will focus on developmental endothelial locus-1 (Del-1), an endogenous inhibitor of leukocyte adhesion.

  • Toll-like receptors (TLRs) playa crucial role in initiating and regulating innate and adaptive immune responses by detecting invading microbial pathogens. TLRs can also respond to non-microbial molecules derived from damaged tissue. Accumulating evidence suggests that deregulation of TLRs results in the dysfunction of immune system and ultimately increases the risk of many immune and inflammatory diseases including infectious diseases, allergy, and autoimmune diseases. Therefore, understanding how the immune system is controlled by TLRs will provide new insight to find the way to prevent or treat infectious diseases and immune disorders.

  • p43 is a protein with complex biological activities. It is first found as a protein associated with macromolecular tRNA synthetase complex. Within this complex, p43 specifically interacts with arginyl-tRNA synthetase to help the substrate tRNA binding to the enzyme. It is also necessary for the cellular stability of arginyl-tRNA synthetase and the molecular association of a few complex-forming tRNA synthetases. (omitted)

  • Multiple sclerosis is an autoimmune demyelinating disorder of the nervous system. The ocular manifestation includes optic neuritis, internuclear opthalmoplegia and nystagmus. Upbeat nystagmus is a rare manifestation of multiple sclerosis. We report a patient with relapsing multiple sclerosis who presented with upbeat nystagmus from a circumscribed lesion in the caudal medulla.

  • Muscle specific tyrosine kinase (MuSK) myasthenia gravis (MG) is a rare subtype of MG, which is immunologically distinct and differential therapeutic response. Though MG is often associated with other autoimmune disorders or malignancy, concurrence of other disease and MuSK MG has been infrequently reported. We present a patient of MuSK MG associated with multicentric Castelman disease.

  • The characteristic features of myasthenia gravis, which are weakness of voluntary muscle and easy fatigability, result from defective neuromuscular transmission caused by an autoimmune response to acetylcholine receptor. Recently, we performed two cases of thymectomy for the treatment of myasthenia gravis, one was 50 year old man who had malignant thymoma and the other was 19 year old girl who had benign thymic hyperplasia. The former had long duration of symptoms, and showed poor postoperative result. The latter had short duration of symptoms, and showed complete remission. Herewith, we suggest that early thymectomy can give the clinical assets for myasthenia gravis. So we report these two experiences with review of literatures.

  • The commitment of T helper (Th) cells to Thl or Th2 cells is of crucial importance with respective to susceptibility or resistance to particular infections, or to autoimmune diseases and allergic diseases. The nature of Thl or Th2 polarizing signals is not yet fully understood. However, the cytokines that are present in the environment of the $CD4^{+}$ T cell at the time it encounters the antigen significantly regulate the differentiation of Th cells into either Thl or Th2 subsets.

  • The immune system is not fully developed in human neonates and infants; breastfeeding is important in this stage as the bioactive components of human breast milk are known to have anti-microbial, anti-inflammatory, and immunomodulatory effects, and can therefore contribute to an infant's immunity against allergies, asthma, autoimmune diseases, and inflammatory bowel disease. Herein, the positive effect on the immune system by human colostrum and milk are reviewed.

  • Immunological imbalance eventually results in the development of various diseases. A typical example is an imbalance of cytokines with immunomodulatory abilities. In this paper, we propose a two-variable delay model to anti-pro-inflammatory cytokine therapy for autoimmune diseases, which are caused by an imbalance between the pro and anti-inflammatory cytokines. The interaction between pro- and anti-inflammatory cytokines were modeled mathematically to investigate the relevance of cytokines in disease processes. The delay time was estimated to maintain the stability of a biologically important steady state. In particular, the effects of delay with anti-pro-inflammatory cytokines therapy in autoinflammatory diseases were studied.
