Researchers define mechanistic basis for functional heterogeneity of tumor-infiltrating B cells with therapeutic implications

A study published in Science reveals two patterns of tumor-infiltrating B cell responses: germinal center-like and extra-follicular. The former is associated with anti-tumor immunity, while the latter is linked to an immunosuppressive tumor microenvironment. Researchers propose targeting atypical memory B cells for cancer immunotherapy.

DGIST develops three-dimensional retinal electrodes in a convex braille shape to partially restore sight in patients with blindness

Researchers at DGIST have developed three-dimensional retinal electrodes with a convex braille shape, which can stimulate remaining normal nerve cells in the retina. This technology aims to partially restore vision to patients with blindness by minimizing distance to cells and reducing current required for stimulation.
