Dry and liquid formulations of IBT-V02, a novel multi-component toxoid vaccine, are effective against isolates from low-to-middle income countries.
is the leading cause of skin and soft tissue infections (SSTIs) in the U.S. as well as more serious invasive diseases, including bacteremia, sepsis, endocarditis, surgical site infections, osteomyelitis, and pneumonia. These infections are exacerbated by the emergence of antibiotic-resistant clinical isolates such as methicillin-resistant (MRSA), highlighting the need for alternatives to antibiotics to treat bacterial infections. We have previously developed a multi-component toxoid vaccine (IBT-V02) in a liquid formulation with efficacy against multiple strains of prevalent in the industrialized world. However, liquid vaccine formulations are not compatible with the paucity of cold chain storage infrastructure in many low-to-middle income countries (LMICs). Furthermore, whether our IBT-V02 vaccine formulations are protective against isolates from LMICs is unknown. To overcome these limitations, we developed lyophilized and spray freeze-dried formulations of IBT-V02 vaccine and demonstrated that both formulations had comparable biophysical attributes as the liquid formulation, including similar levels of toxin neutralizing antibodies and protective efficacy against MRSA infections in murine and rabbit models. To enhance the relevancy of our findings, we then performed a multi-dimensional screen of 83 clinical isolates from LMICs (e.g., Democratic Republic of Congo, Palestine, and Cambodia) to rationally down-select strains to test in our models based on broad expression of IBT-V02 targets (i.e., pore-forming toxins and superantigens). IBT-V02 polyclonal antisera effectively neutralized toxins produced by the clinical isolates from LMICs. Notably, the lyophilized IBT-V02 formulation exhibited significant efficacy in various preclinical infection models against the clinical isolates from LMICs, which was comparable to our liquid formulation. Collectively, our findings suggested that lyophilization is an effective alternative to liquid vaccine formulations of our IBT-V02 vaccine against infections, which has important implications for protection from isolates from LMICs.Yu Wang, Ipsita Mukherjee, Arundhathi Venkatasubramaniam, Dustin Dikeman, Nicholas Orlando, Jing Zhang, Roger Ortines, Mark Mednikov, Shardulendra P Sherchand, Tulasikumari Kanipakala, Thao Le, Sanjay Shukla, Mark Ketner, Rajan P Adhikari, Hatice Karauzum, M Javad Aman, Nathan K Archer

Development and validation of streptavidin-biotin-based double antibody sandwich ELISA for ricin diagnosis.
Ricin is a potential biowarfare agent. It is a phytotoxin isolated from castor seeds. At present there is no antidote available for ricin poisoning, patients only get supportive treatment based on their symptoms. This highlights the importance of early detection to avoid severity of accidents and reduce the risk factor. Considering this, our study aimed to develop a highly sensitive and specific sandwich ELISA for the detection of ricin.Shivani Dixit, Jagrati Parashar, Ram Kumar Dhaked, Abdhesh Kumar, Nandita Saxena

Moniezia benedeni infection increases IgE cells in sheep (Ovis aries) small intestine.
The concentration of immunoglobulin (Ig) E is the lowest among serum Igs, but it can induces type I hypersensitivity and plays an important role in anti-parasitic infection. The present study aimed to explore the residence characteristics of IgE cells in the sheep small intestine and the impact of Moniezia benedeni infection on them. The recombinant plasmids pET-28a-IgE were constructed and induced and expressed in Escherichia coli. BL21 (DE3). The rabbit anti-sheep IgE polyclonal antibody was prepared using the obtained recombinant protein as antigen. Finally, the levels of IgE cells in the small intestine of healthy (Control group) and naturally M. benedeni-infected (Infected group) sheep were detected analyzed. The results showed that the rabbit anti-sheep IgE polyclonal antibody with good immunogenicity (titer = 1: 128000) could specifically bind to the heavy chain of natural sheep IgE. In the Control group, the IgE cells were mainly distributed in lamina propria of the small intestine, and the densities were significantly decreased from duodenum to ileum (P<0.05), with respective values of (4.28 cells / 10 μm, 1.80 cells / 10 μm, and 1.44 cells / 10 μm in duodenum, jejunum, and ileum. In the Infected group, IgE cells density were 6.26 cells / 10 μm, 3.01 cells / 10 μm, and 2.09 cells / 10 μm in duodenum, jejunum and ileum respectively, which were significantly higher in all segments compared to the Control group (P<0.05), increasing by 46.26%, 67.22% and 45.14%, respectively. In addition, compared with the Control group, the IgE protein levels were significantly increased in all intestinal segments of the Infected group (P<0.01), however, there was no significant differences among the different intestinal segments within the same group (P>0.05). The results demonstrated that M. benedeni infection could significantly increase the content of IgE and the distribution density of its secreting cells in sheep small intestine. The intestinal mucosal immune system of sheep presented obvious specificity against M. benedeni infection. This lays a good foundation for further exploring molecular mechanisms of the intestinal mucosal immune system monitoring and responding to M. benedeni infection.Jing Pan, Wan-Ling Yao, Li-Ping Liu, Bao-Shan Wang, Wen-Zhu Chai, Zhen Huang, Xi-Ping Fan, Wan-Hong He, Wen-Hui Wang, Wang-Dong Zhang

First-in-human Study With LIS1, a Next-generation Porcine Low Immunogenicity Antilymphocyte Immunoglobulin in Kidney Transplantation.
Polyclonal rabbit antithymocyte globulins (ATGs) are commonly used in organ transplantation as induction. Anti-N-glycolylneuraminic acid carbohydrate antibodies which develop in response to rabbit carbohydrate antigens might lead to unwanted systemic inflammation. LIS1, the first new generation of antilymphocyte globulins (ALGs) derived from double knockout swine, lacking carbohydrate xenoantigens was already tested in nonhuman primates and rodent models.Ondrej Viklicky, Janka Slatinska, Libor Janousek, Juliette Rousse, Pierre-Joseph Royer, Pierre-Louis Toutain, Emanuele Cozzi, Cesare Galli, Gwenaelle Evanno, Odile Duvaux, Jean-Marie Bach, Jean-Paul Soulillou, Magali Giral, Bernard Vanhove, Gilles Blancho

Kv 11.1 Expression Is Associated With Malignancy of Canine Mammary Gland Tumors.
The expression level of the voltage-dependent potassium channel Kv 11.1 was shown to be associated with the clinicopathological features, aggressiveness, and prognosis of human breast cancer. Canine mammary gland tumor (cMGT) is the most common tumor type in intact female dogs; however, the significance of Kv 11.1 in cMGT is unknown. The aim of this study was to identify Kv 11.1 expression in 57 benign and malignant cMGT tissues from dogs and to investigate the correlation of Kv 11.1 expression with the clinicopathological parameters and prognosis of cMGT.Nuri Lee, Sungin Lee, Wanhee Kim

Discovery of Two Novel Immunoepitopes and Development of Peptide-based Sarcoidosis Immunoassay.
Sarcoidosis is a systemic granulomatous disorder associated with hypergammaglobulinemia and the presence of autoantibodies. The specific antigens initiating granulomatous inflammation in sarcoidosis are unknown and there is no specific test available to diagnose sarcoidosis. To discover novel sarcoidosis antigens, we developed a high-throughput T7 phage display library derived from the sarcoidosis cDNA and identified numerous clones differentiating sarcoidosis from other respiratory diseases. After clone sequencing and homology search, we identified two epitopes (Cofilinμ and Chain A) that specifically bind to serum IgGs of sarcoidosis patients.Changya Peng, Jaya Talreja, Brennen Steinbauer, Kazuhiko Shinki, Laura L Koth, Lobelia Samavati
