Are i‐Motif Structures in DNA Compatible with Cytosine–Ag(I)–Cytosine Base Pairs?

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
An i‐motif/duplex junction was evaluated with respect to its ability to replace the protons from the hemi‐protonated C:CH+ pairs by AgI ions to form C–AgI–C base pairs. Interestingly, only one such metal‐mediated base pair can be formed before the oligonucleotide rearranges into a duplex structure.

Key role for inhibins in effective T cell activation, migration and Th17 differentiation

open access: yesFEBS Open Bio, Volume 16, Issue 1, Page 79-89, January 2026.
Activins/inhibins modulate immune responses. Here, we show that inhibins can be produced very early after T cell activation and can act in an autocrine way, favoring Th1 versus Th17 differentiation and CCL19/CCL21 mediated migration. Recombinant inhibin A can restore the Th1/Th17 balance, highlighting the role of inhibins as key regulators of T cell ...

Inducing Chirality and Chiral Instabilities in Ferrogels with Homogenous Magnetic Fields

open access: yesAdvanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
By pre‐aligning magnetic particles into chains, significant chiral deformations are induced by fixing the base of a cylindrical actuator and applying a homogeneous magnetic field. Subsequent base rotation can drive the system into metastable states. Further rotation or reduction of field strength triggers a chiral instability, characterized by a switch

Bi‐Functional Topospecific Nanoparticles to Promote Immune‐Tumor Cell Engagement as A New Immunotherapeutic Strategy

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
A Janus‐engineered nanoplatform (J‐pHLIP‐PD1), featuring separate tumor‐ and immune‐targeting faces, bridges melanoma cells and cytotoxic T lymphocytes using toposelective pHLIP and anti‐PD‐1 presentation. This strategy elicits robust antitumor responses, promotes immunogenic tumor cell death, suppresses lung metastasis in vivo, and provides a modular,
