Research Articles
- The 20S proteasome core, active within apoptotic exosome-like vesicles, induces autoantibody production and accelerates rejection
Exosome-like vesicles containing an active 20S proteasome core contribute to autoimmunity and vascular allograft inflammation.
- Implantable synthetic cytokine converter cells with AND-gate logic treat experimental psoriasis
Implantable designer cells sense proinflammatory cytokines and coordinate production and delivery of anti-inflammatory molecules to attenuate psoriasis in mice.
- Therapeutic targeting of casein kinase 1δ in breast cancer
Casein kinase 1δ promotes breast tumorigenesis by activation of β-catenin and can be targeted in some breast cancers.
- Improving the spatial resolution of epiretinal implants by increasing stimulus pulse duration
Retinal implants that deliver longer pulses of electrical current may markedly improve image sharpness for blind individuals.

About The Cover

ONLINE COVER It's Logical. There's no cure for psoriasis, an inflammatory skin disease that is itchy, red, and scaly. In this issue, Fussenegger and colleagues describe a potential new treatment for psoriasis using synthetic biology tools. The authors engineered human cells to contain AND logic gates, where two inputs—cytokines overexpressed in psoriasis, IL-22 and TNF—triggered the cell's machinery to produce two therapeutic cytokine outputs, IL-4 and IL-10. When implanted in mice, the so-called cytokine converter cells responded to acute and established disease, reducing the severity of psoriatic lesions for days. [CREDIT: C.
