Cryptosporidium infection of human small intestinal epithelial cells induces type III interferon expression and impairs the infectivity of live-attenuated rotavirus vaccines [hALI_Cp]

Project description:We developed a stem cell-derived culture system for C. hominis using human enterocytes differentiated under air-liquid interface (ALI) conditions. Human ALI (hALI) cultures supported robust growth and complete development of C. hominis in vitro including all life cycle stages. C. hominis infection induced a strong interferon response from enterocytes, likely driven by an endogenous dsRNA virus in the parasite. Prior infection with Cryptosporidium induced type III IFN secretion and consequently blunted infection with Rotavirus, suggesting such co-infections may alter vaccine efficacy.

<i>Cryptosporidium</i> infection of human small intestinal epithelial cells induces type III interferon and impairs infectivity of Rotavirus.

Project description:Cryptosporidiosis is a major cause of severe diarrheal disease in infants from resource poor settings. The majority of infections are caused by the human-specific pathogen C. hominis and absence of in vitro growth platforms has limited our understanding of host-pathogen interactions and development of effective treatments. To address this problem, we developed a stem cell-derived culture system for C. hominis using human enterocytes differentiated under air-liquid interface (ALI) conditions. Human ALI cultures supported robust growth and complete development of C. hominis in vitro including all life cycle stages. Cryptosporidium infection induced a strong interferon response from enterocytes, possibly driven, in part, by an endogenous dsRNA virus in the parasite. Prior infection with Cryptosporidium induced type III IFN secretion and consequently blunted infection with Rotavirus, including live attenuated vaccine strains. The development of hALI provides a platform for further studies on human-specific pathogens, including clinically important coinfections that may alter vaccine efficacy.

Overview of the Development, Impacts, and Challenges of Live-Attenuated Oral Rotavirus Vaccines.

Project description:Safety, efficacy, and cost-effectiveness are paramount to vaccine development. Following the isolation of rotavirus particles in 1969 and its evidence as an aetiology of severe dehydrating diarrhoea in infants and young children worldwide, the quest to find not only an acceptable and reliable but cost-effective vaccine has continued until now. Four live-attenuated oral rotavirus vaccines (LAORoVs) (Rotarix®, RotaTeq®, Rotavac®, and RotaSIIL®) have been developed and licensed to be used against all forms of rotavirus-associated infection. The efficacy of these vaccines is more obvious in the high-income countries (HIC) compared with the low- to middle-income countries (LMICs); however, the impact is far exceeding in the low-income countries (LICs). Despite the rotavirus vaccine efficacy and effectiveness, more than 90 countries (mostly Asia, America, and Europe) are yet to implement any of these vaccines. Implementation of these vaccines has continued to suffer a setback in these countries due to the vaccine cost, policy, discharging of strategic preventive measures, and infrastructures. This review reappraises the impacts and effectiveness of the current live-attenuated oral rotavirus vaccines from many representative countries of the globe. It examines the problems associated with the low efficacy of these vaccines and the way forward. Lastly, forefront efforts put forward to develop initial procedures for oral rotavirus vaccines were examined and re-connected to today vaccines.

Transcriptional responses to oral live attenuated typhoid vaccines

Project description:Enteric fever is a major public health problem and causes numerous deaths annually. Ty21a is the only efficacious oral, live attenuated typhoid vaccine currently licensed for use, however, its mechanism of protection is poorly understood. To address this knowledge gap, we interrogated transcriptional profiles following vaccination with Ty21a and an immunogenic experimental oral live attenuated vaccine, M01ZH09, and related these findings to immunogenicity, and incubation period and disease severity following challenge with Salmonella Typhi four weeks after vaccination. Despite originating from the same parent strain (Ty2), we detected marked differences in the gene expression between both vaccines. Analysis of the transcriptome 7 days after M01ZH09 vaccination implicated transcriptional patterns associated with the cell cycle correlated significantly with humoral immunogenicity 28 days after vaccination. In contrast, significantly induced T and NK cell responses were associated with Ty21a vaccination, and integrative analysis indicated signatures reflecting amino acid metabolism with delayed onset of disease. Stimulation of PBMCs collected from participants prior to and following vaccination with the two vaccine strains in vitro confirmed the superior capacity of Ty21a to induce NK cells, validating gene expression results. These data provide insight into the effects of oral live attenuated typhoid vaccines on the human molecular immune response and underline the involvement of T cell response signatures with protection following challenge.

Live-attenuated respiratory syncytial virus vaccines.

Project description:Live-attenuated respiratory syncytial virus (RSV) vaccines offer several advantages for immunization of infants and young children: (1) they do not cause vaccine-associated enhanced RSV disease; (2) they broadly stimulate innate, humoral, and cellular immunity, both systemically and locally in the respiratory tract; (3) they are delivered intranasally; and (4) they replicate in the upper respiratory tract of young infants despite the presence of passively acquired maternally derived RSV neutralizing antibody. This chapter describes early efforts to develop vaccines through the classic methods of serial cold-passage and chemical mutagenesis, and recent efforts using reverse genetics to derive attenuated derivatives of wild-type (WT) RSV and to develop parainfluenza vaccine vectors that express RSV surface glycoproteins.

Live attenuated vaccines for invasive Salmonella infections.

Project description:Salmonella enterica serovar Typhi produces significant morbidity and mortality worldwide despite the fact that there are licensed Salmonella Typhi vaccines available. This is primarily due to the fact that these vaccines are not used in the countries that most need them. There is growing recognition that an effective invasive Salmonella vaccine formulation must also prevent infection due to other Salmonella serovars. We anticipate that a multivalent vaccine that targets the following serovars will be needed to control invasive Salmonella infections worldwide: Salmonella Typhi, Salmonella Paratyphi A, Salmonella Paratyphi B (currently uncommon but may become dominant again), Salmonella Typhimurium, Salmonella Enteritidis and Salmonella Choleraesuis (as well as other Group C Salmonella). Live attenuated vaccines are an attractive vaccine formulation for use in developing as well as developed countries. Here, we describe the methods of attenuation that have been used to date to create live attenuated Salmonella vaccines and provide an update on the progress that has been made on these vaccines.
