Principles of prevention of infectious diseases have been known for several thousands of years. One of the most significant tools of infection prophylaxis is immunization. Vaccines containing thymus-dependent antigens produce massive and complex immune response and feature immunologic memory. That is why they can successfully protect patients with diabetes. Lately, it has been thought by general public and even experts that application of vaccines within national immunization programmes is one of the etiopathogenetic factors in the development of type 1 diabetes mellitus (DM). However, analysis of extensive studies performed by the experts of the Institute for Vaccine Safety proved that there is no positive or negative impact of immunization on the development of type 1 diabetes mellitus. The basic vaccinations recommended for diabetics include immunizations against influenza, pneumococcal infections, tetanus and viral hepatitis B. Other vaccines are administered only after individual assessment of benefits and risks for the diabetic patient. Most often, these are vaccinations against viral hepatitis A, tick-borne encephalitis, meningococcal infections and other infections that put in risk diabetic patients travelling abroad.

Although it is well-documented from theoretical studies that pathogens have the capacity to generate cycles, the occurrence and role of pathogens and disease have been poorly empirically studied in cyclic voles and lemmings. In screening for the occurrence of disease in cyclic vole and lemming populations, we found that a high proportion of live-trapped Clethrionomys glareolus, C. rufocanus, Microtus agrestis and Lemmus lemmus at high collective peak density, shortly before the decline, suffered from diabetes or myocarditis in northern Scandinavia. A high frequency of animals had abnormal blood glucose (BG) levels at the time of trapping (5-33%). In contrast, C. rufocanus individuals tested at a much lower overall density, and at an earlier stage relative to the decline in the following cycle, showed normal BG concentrations. However, a high proportion (43%) of a sample of these individuals kept in captivity developed clinical diabetes within five weeks, as determined by BG levels and a glucose tolerance test performed at that later time. A new picornavirus isolated from the rodents, Ljungan virus (LV), was assumed to cause the diseases, as LV-induced diabetes and myocarditis, as well as encephalitis and fetal deaths, were observed in laboratory mice. We hypothesize that LV infection significantly affects morbidity and mortality rates in the wild, either directly or indirectly, by predisposing the rodents to predation, and is at least involved in causing the regular, rapid population declines of these cyclic voles and lemmings. Increased stress at peak densities is thought to be an important trigger for the development of disease, as the occurrence of disease in laboratory mice has been found to be triggered by introducing stress to LV-infected animals.

Amyloidosis comprises a group of diseases characterized by the deposition of insoluble protein fibrils in specific organs and includes several serious medical disorders, such as Alzheimer's disease, prion-associated transmissible spongiform encephalitis, and type II diabetes. Despite the structural dissimilarity between the soluble proteins and peptides, these fibrils exhibit similar morphologies under electron microscopy with a characteristic "cross beta-sheet" pattern examined by x-ray fiber diffraction experiments. Many studies have revealed that each of these diseases is associated to a specific protein that is partially unfolded, misfolded, and aggregated. However, the detailed structures of the causative agents and the toxicity mechanisms are less known. This review summarizes recent studies in the conformational disorders leading to aggregation; including which proteins potentially cause conformational diseases, the aggregation mechanisms of these proteins, and recent researches on the conformational changes using advanced experiments or molecular dynamics simulations. Finally, current drug designs towards these protein conformational diseases are also discussed. It is believed that the advances in basic understanding of the mechanisms of conformational changes as well as biological functions of these proteins will shed light on the development and design of potential interfering compounds against amyloid formation associated with protein conformational diseases.

We describe a patient with Ramsay Hunt syndrome and varicella-zoster virus encephalitis. The coexistence of these conditions is rare and to our knowledge has not been clearly documented in the English-language literature. We summarize the clinical characteristics of our patient and seven similar patients described in previous reports, including those published in Japanese. Although concomitant diseases such as diabetes and chronic renal failure may lead to an aggressive course, all patients described in detail have had good outcomes.

Immune-mediated diseases (e.g. inflammatory bowel disease, asthma, multiple sclerosis and autoimmune diabetes) are increasing in prevalence and emerge as populations adopt meticulously hygienic lifestyles. This change in lifestyles precludes exposure to helminths (parasitic worms). Loss of natural helminth exposure removes a previously universal Th2 and regulatory immune biasing imparted by these organisms. Helminths protect animals from developing immune-mediated diseases (colitis, reactive airway disease, encephalitis and diabetes). Clinical trials show that exposure to helminths can reduce disease activity in patients with ulcerative colitis or Crohn's disease. This paper summarises work by multiple groups demonstrating that colonization with helminths alters immune reactivity and protects against disease from dysregulated inflammation.

Anti-CD3 monoclonal antibody (mAb) has been shown to induce tolerance and to be an effective treatment for diabetes both in animal models and in human trials. We have shown that anti-CD3 mAb given orally is biologically active in the gut and suppresses experimental autoimmune encephalitis by the induction of a regulatory T-cell that expresses latency-associated peptide (LAP) on its surface. In the present study, we investigated the effect of oral anti-CD3 mAb on the prevention of autoimmune diabetes in AKR mice in which the low-dose streptozocin (STZ) model induces autoimmunity to the beta-cells of the islets. We found that oral anti-CD3 mAb given at doses of 50 and 250 microg/feeding suppressed the incidence of diabetes in this model with the best effects seen at the 50 microg/dose. Associated with suppression, we observed decreased cell proliferation in the spleen and conversion of T-helper (Th)1 responses into Th2/Th3 responses in the periphery, including the pancreatic lymph nodes. Oral anti-CD3 mAb increased the expression of LAP on CD4(+) T-cells, and these cells could adoptively transfer protection. Protection by oral anti-CD3 was transforming growth factor-beta dependent. Our results demonstrate that oral anti-CD3 is effective in the model of STZ-induced diabetes and may be a useful form of therapy for type 1 diabetes in humans.

Fungal infections of the central nervous system (CNS) are rare in the general population and are invariably secondary to primary focus elsewhere, usually in the lung or intestine. Except for people with longstanding diabetes, they are most frequently encountered in immunocompromised patients such as those with acquired immunodeficiency syndrome or after organ transplantation. Due to the lack of inflammatory response, neuroradiological findings are often nonspecific and are frequently mistaken for tuberculous meningitis, pyogenic abscess or brain tumor. Intracranial fungal infections are being identified more frequently due to the increased incidence of AIDS patients, better radiological investigations, more sensitive microbiological techniques and better critical care of moribund patients. Although almost any fungus may cause encephalitis, cryptococcal meningoencephalitis is most frequently seen, followed by aspergillosis and candidiasis. The biology, epidemiology and imaging features of the common fungal infections of the CNS will be reviewed. The radiographic appearance alone is often not specific, but the combination of the appropriate clinical setting along with computed tomography or magnetic resonance may help to suggest the correct diagnosis.

Toll-like receptors (TLRs) form a large family of pattern recognition receptors with at least 11 members in human and 13 in mouse. TLRs recognize a wide variety of microbial components and potential host-derived agonists that have emerged as key mediators of innate immunity. TLR signaling also plays an important role in the activation of the adaptive immune system by inducing proinflammatory cytokines and upregulating costimulatory molecules of antigen presenting cells. The dysregulation of TLR signaling may cause autoimmunity. This review discusses the contribution of TLR signaling to the initiation and progression of autoimmune diseases, such as rheumatoid arthritis, experimental autoimmune encephalitis, myocarditis, hepatitis, kidney disease, systemic lupus erythematosus, diabetes, obesity, and experimental autoimmune uveitis as well as aging. The involvement of TLR signaling in the pathogenesis of autoimmune diseases may provide novel targets for the development of therapeutics.
