Targeting platelet inhibition receptors for novel therapies: PECAM-1 and G6b-B.

While current oral antiplatelet therapies benefit many patients, they deregulate the hemostatic balance leaving patients at risk of systemic side-effects such as hemorrhage. Dual antiplatelet treatment is the standard approach, combining aspirin with P2Y blockers. These therapies mainly target autocrine activation mechanisms (TxA, ADP) and, more recently, the use of thrombin or thrombin receptor antagonists have been added to the available approaches.

TRIM46 Organizes Microtubule Fasciculation in the Axon Initial Segment.

Selective cargo transport into axons and dendrites over the microtubule network is essential for neuron polarization. The axon initial segment (AIS) separates the axon from the somatodendritic compartment and controls the microtubule-dependent transport into the axon. Interestingly, the AIS has a characteristic microtubule organization; it contains bundles of closely spaced microtubules with electron dense cross-bridges, referred to as microtubule fascicles.
