Key Highlights
•
Scientists have discovered that a specific version of the KIF3B motor protein complex is specialized to transport a key protein called TRIM46 to the axon initial segment, a critical part of a neuron. This finding reveals how cells use different combinations of transport machinery to ensure proteins get to the right place, which is essential for building a properly functioning nervous system.

A new small-molecule drug that blocks the CBLB enzyme prevents the tagging of the Epidermal Growth Factor Receptor (EGFR) for degradation, which in turn reduces how much the receptor is pulled into the cell and weakens signals that drive cell movement. This research provides a potential new strategy for controlling cell behaviors driven by EGFR, which is often involved in cancer growth and spread.

A new CAR T cell therapy targeting a protein called uPAR, when combined with drugs that induce cellular senescence, can eliminate both primary and metastatic solid tumors in lab models by attacking both cancer cells and their surrounding support tissue. This dual-targeting approach overcomes a major hurdle in solid tumor treatment and shows promise for broader application with reduced side effects on the bone marrow.
