Rohu (Labeo rohita), an Indian Major Carp (IMC) is an economically important aquaculture species in India. Inspite of the technological advances, infectious diseases caused by viruses, bacteria and parasites have been a major limiting factor in the development and profitability of fish farms. At present, information regarding the immune status of the Indian major carps is limited. This lack of knowledge is a major impediment for establishment of effective preventive measures against broad spectrum of infectious agents...

Pythiosis is a severe and life-threatening disease that affects humans and various animal species. We report a model of vascular/disseminated pythiosis occurring after subcutaneous inoculation of 2 x 104 Pythium insidiosum zoospores/mL in immunocompromised BALB/c mice. For this model, we carried out two rounds of experiments. First, we evaluated two protocols of immunosuppression before inoculation: cyclophosphamide at 150 mg/kg (CYP group) and cyclophosphamide 200 mg/kg plus hydrocortisone acetate at 250 mg/kg (CYP+HCA group)...

In patients whom are highly sensitized immunologically, the benefit of kidney transplantation can be extended to this population through the utilization of organs from human leukocyte antigen incompatible (HLAi) donors. This retrospective observational study was designed to identify the incidence and predictors of acute antibody-mediated rejection/acute cellular rejection (AMR/ACR) in our kidney recipients from living kidney donors (sensitized and those with low immunologic risk). This single-center study has been conducted at King Fahad Specialist Hospital, Dammam (KFSH-D), Saudi Arabia; during the period of September 2008- August 2013...

Leptospirosis is an emerging worldwide zoonosis caused by pathogenic Leptospira spp. Our understanding of leptospirosis pathogenesis and host immune response remains limited, while mechanistic studies are hindered by a lack of proper animal models and immunological reagents. Here we established a murine model of acute and self-resolving leptospirosis by infecting 10-week-old C57BL/6 mice with Leptospira interrogans serovar Autumnalis strain 56606v, with characteristic manifestations including jaundice as well as subcutaneous and pulmonary bleeding, but no kidney lesions...

Despite advances in testing compatibility between donor and recipient, graft rejection remains a current concern. Single-nucleotide polymorphisms (SNPs) that codify altered enzymes of metabolism, drug transport, and the immune system may contribute to graft rejection in transplant patients. This study examined the association between SNPs present in genes of these processes and occurrence of graft rejection episodes in 246 kidney transplant patients, 35% of which were diagnosed with rejection. Genotype-gene expression associations were also assessed...

REVIEW
Katayoun Behnam Sani, Birgit Sawitzki
Ever since its first application in clinical medicine, scientists have urged to induce tolerance towards foreign allogeneic transplants and thus avoid rejection by the recipient's immune system. This would circumvent chronic use of immunosuppressive drugs (IS) and thus avoid development of IS-induced side effects, which are contributing to the still unsatisfactory long-term graft and patient survival after solid organ transplantation. Although manifold strategies of tolerance induction have been described in preclinical models, only three therapeutic approaches have been successfully utilized in a still small number of patients...

Islet transplantation offers a minimally-invasive approach for beta cell replacement in diabetic patients with hypoglycemic unawareness. Attempts at insulin independence may require multiple islet re-infusions from distinct donors, thus increasing the risk for allogeneic sensitization. Currently, solid organ pancreas transplant is the only remaining surgical option following failed islet transplantation in the US. However, the immunologic impact of repeated exposure to donor antigens on subsequent pancreas transplantation is unclear...

DNA vaccines had been widely used against microbial infection in animals. The use of molecular adjuvants to improve the immunogenicity of DNA vaccines has been increasingly studied in recent years. MyD88 is one of the adapter molecules to activate the signaling cascades and produces inflammatory mediators, and its immunological role and adjuvant potential which had been proved in mammals were rarely reported in fish species. In this study, plasmid pcMyD88 was constructed and the capacity of MyD88 as molecular adjuvant was explored by co-injecting with a DNA vaccine encoding AcfA against Vibrio alginolyticus infection in orange spotted grouper...

BACKGROUND: Sepsis is a life-threatening complication of an infection and remains one of the leading causes of mortality in surgical patients. Bacteremia induces excessive inflammatory responses that result in multiple organ damage. Chronic helminth infection and helminth-derived materials have been found to immunomodulate host immune system to reduce inflammation against some allergic or inflammatory diseases. Schistosoma japonicum cystatin (Sj-Cys) is a cysteine protease inhibitor that induces regulatory T-cells and a potential immunomodulatory...

Feline morbillivirus (FeMV), a member of the family Paramyxoviridae, is an emerging virus that was discovered in 2012. Despite the importance of FeMV infection in cats because of its postulated involvement in kidney diseases, no simple serological assay has been reported in its detection. Here, FeMV phosphoprotein (P protein) was expressed and purified as a glutathione-S-transferase (GST)-fusion protein and used for an enzyme-linked immunosorbent assay (ELISA) to detect FeMV-specific antibodies. With a cutoff value determined by immunoblotting, anti-FeMV P protein was detected with this assay in 22 (22%) of the 100 cat plasma samples collected from various regions of Japan...
