Primary human intestinal organoids recapitulate enteric infection of monkeypox virus and enable scalable drug discovery

Project description:Monkeypox virus (MPXV) infection-associated intestinal manifestations including diarrhea and proctitis have been frequently reported during mpox outbreaks. The clade IIb MPXV strain has caused the 2022-2023 global outbreak, whereas the Ia and Ib strains are causing the concurrent outbreaks in Africa. Here, we found clinical evidence that MPXV can directly infect human intestine to induce lesions. Intriguingly, primary organoids cultured from human ileum and rectum support productive infections of MPXV clade IIb, Ia and Ib strains. Upon differentiation, we found that enterocytes and goblet cells but not enteroendocrine cells are capable of supporting viral replication. Given that primary intestinal organoids can be rapidly expanded in large scale, we were able to screen a broad-spectrum antiviral drug library. We identified 12 leading candidates of safe-in-human agents including clinically used drugs such as clofarabine. We extensively validated the anti-MPXV activity of clofarabine in human intestinal and skin organoids, and consistently demonstrated the potent antiviral activity against clade Ia, Ib and IIb strains. These findings are important for better understanding the clinical manifestations of mpox. Primary intestinal organoids-based infection models and the established antiviral drug discovery pipeline bear major implications in responding to the current mpox global health emergency, and sustaining epidemic poxvirus preparedness.

Infection of MK2 cells with monkeypox virus

Project description:Orthopox viruses, including monkeypox, multiply intracellularly and induce numerous changes in host genes expression. The virus target mainly humoral host response, and simultaneously, exploits other genes and functions to reproduce effectively. The goal of this experiment is to identify those host genes and functions that are essential for monkeypox virus replication. Mock infected control cells were treated and incubated identically to time point arms, except for virus exposure. Two time points of cells infected with monkeypox virus were harvested at 3, 7 hours post infection, and gene expression was assessed using microarray in all arms. The experiment was done in triplicate.

A generic, cost-effective and scalable cell lineage analysis platform

Project description:Advances in single-cell genomics enable commensurate improvements in methods for uncovering lineage relations among individual cells. Current sequencing based methods for cell lineage analysis depend on low resolution bulk analysis or rely on extensive single cell sequencing which is not scalable and could be biased by functional dependencies. Here we show an integrated biochemical-computational platform for generic single-cell lineage analysis that is retrospective, cost-effective and scalable. It consists of a biochemical-computational pipeline that inputs individual cells, produces targeted single-cell sequencing data and uses it to generate a lineage tree of the input cells. We validated the platform by applying it to cells sampled from an ex vivo grown tree and analyzed its feasibility landscape by computer simulations. We conclude that the platform may serve as a generic tool for lineage analysis and thus pave the way towards large-scale human cell lineage discovery.

Polyvalent mRNA vaccination elicited potent immune response to monkeypox surface antigens

Project description:The soaring global monkeypox cases lead to a surge in demand for monkeypox vaccine, which far exceeds the supply. mRNA vaccine has achieved great success in prevention of coronavirus disease and holds promise against diverse pathogens. In this study, we generate a polyvalent lipid nanoparticle (LNP) mRNA vaccine candidate for monkeypox virus (MPXV) and evaluate its immunogenicity in animal models. This polyvalent MPXV mRNA vaccine candidate, MPXVac-097, encodes five 2022 MPXV targets that are important surface antigens. Three-dose (prime-boost-booster) MPXVac-097 vaccination elicits strong antibody response to A35R and E8L antigens, moderate response to M1R, but not B6R or A29, highlighting the differences in immunogenicity. Bulk T cell receptor (TCR) sequencing reveals preferential usage of VJ combinations and clonal expansion of peripheral T cells after MPXVac-097 vaccination. These data demonstrate initial feasibility of developing MPXV mRNA vaccine and pave the way for its future optimization.
