Design of an exclusive obligate symbiosis for organism-based biological containment.

Biological containment is a critical safeguard for genetically engineered microbes prior to their environmental release to prevent proliferation in unintended regions. However, few biocontainment strategies can support the longer-term microbial survival that may be desired in a target environment without repeated human intervention. Here, we introduce the concept of an orthogonal obligate commensalism for the autonomous creation of environments that are permissive for survival of a biocontained microbe.

The Impact of Cell-Intrinsic STAT6 Protein on Donor T Cell-Mediated Graft-Versus-Tumor Effect.

Bone marrow transplantation (BMT) is mainly performed to restore an anti-tumor immune response, called the graft-versus-tumor (GVT) effect, against leukemia, myeloma and lymphoma. This GVT reactivity is driven by donor T cells, and it can also cause lethal graft-versus-host disease (GVHD). We previously demonstrated that the colonization of mice with helminths preserves the GVT response while suppressing GVHD.

Jan and mini-Jan, a model system for potato functional genomics.

Potato () is the third most important food crop in the world. Although the potato genome has been fully sequenced, functional genomics research of potato lags relative to other major food crops due primarily to the lack of a model experimental potato line. Here, we present a diploid potato line, 'Jan', which possesses all essential characteristics for facile functional genomics studies.

Relationships between neurodivergence status and adverse childhood experiences, and impacts on health, wellbeing, and criminal justice outcomes: findings from a regional household survey study in England.

Background: Evidence indicates that neurodivergent (ND) populations may be more at risk of experiencing adverse childhood experiences (ACEs), compared to neurotypical (NT) populations. However, this evidence has typically not examined a comprehensive set of ACEs and has only included ND individuals on the basis that they have a diagnosis. Very little research has examined the impacts of ACEs on negative adulthood outcomes for ND populations.

Tragedy of the commons: the resource struggle during Plasmodium infection.

Plasmodium spp. have an ancient history with humans, having been described in ancient texts dating back 3500 years ago, which has led to an evolutionary arms race between Plasmodium and humans with Plasmodium successfully subverting durable, sterilizing host immunity. Mechanisms of immune evasion include polymorphism and antigenic variation, as well as dysregulated immune responses, each facilitating transmission and Plasmodium parasite persistence.
