Abstract Background: The development of protective vaccines for Brucella spp. has been hampered by the difficulty in transformation of Brucella cells with foreign DNA for genetic manipulation. It seems that the formation of Brucella spheroplasts would increase the efficiency of transformation. The aim of this study was to devise an efficient method for the transformation of Brucella spp. Materials and Methods: At first, spheroplast of Brucella was prepared by glycine and ampicillin induction and transformed using optimized protocols of CaCl2, electroporation, and lipofection methods. Then, the efficacy of tra...

So, tends to develop a more effective vaccine to prevent this disease is extremely needed and would be so prominent. The novel dense granule antigen 14 (GRA14) has been identified as a potential vaccine candidate a...

Standard treatments include surgery and chemotherapy, however immunotherapy using Dendritic Cell (DC) vaccines is also recognized as an effective treatment for many cancers including colorectal cancer. DCs are the most potent antig...

Publication date: Available online 15 June 2019Source: Nano TodayAuthor(s): Weijing Yang, Zijian Zhou, Joseph Lau, Shuo Hu, Xiaoyuan ChenAbstractImmunotherapy (e.g., checkpoint blockade, adoptive T cell therapy, cancer vaccine) has emerged as one of the most important treatment modalities for cancer in the past two decades. While these approaches are promising, the response rates observed in clinical trials are less than 30% due to tumor heterogeneity and complexity of the tumor microenvironment. Smart nanosystems have the potential to address some of the limitations associated with immunotherapy. Herein, we review applica...

CONCLUSION: Both meningococcal conjugate vaccines showed good immunogenicity in healthy Korean adults without statistically significant differences. Further investigations for serotype distribution of circulating meningococci and the immune interference between other diphtheria toxin-containing vaccines concomitantly used for military recruits are needed to optimize immunization policies.

We examined the role of maternal HIV disease progression, infant factors, placental Fc receptor expression, IgG subclass, and glycan signatures and their association with placental IgG transfer efficiency. Maternal IgG characteristics, such as binding to placentally expressed Fc receptors FcγRIIa and FcγRIIIa, and Fc region glycan profiles were associated with placental IgG transfer efficiency. Our findings suggest that Fc region characteristics modulate the selective placental transfer of IgG, with implications for maternal vaccine design and infant health.Graphical Abstract

Publication date: Available online 13 June 2019Source: EpidemicsAuthor(s): Giorgio GuzzettaAbstractA major outbreak of Hepatitis A Virus (HAV) has swept through Europe between mid-2016 and 2017, mainly within the community of men who have sex with men (MSM). Over the same period, about 1,000 outbreak-related cases of acute Hepatitis A (AHA) were recorded in Lazio region, Italy.We calibrated a Bayesian model to reconstruct likely transmission events within all 44 households where multiple infections were recorded, representing a total of 103 cases from the HAV outbreak in Lazio. Based on information on the observed times of...
