Functional Polarization of Liver Macrophages by Glyco Gold Nanoparticles.

Macrophages are crucial drivers of innate immunity. Reprogramming macrophages to a restorative phenotype in cancer or autoimmune diseases can stop their cancer-promoting activity or trigger anti-inflammatory immunity. Glycans have emerged as key components for immunity as they are involved in many pathophysiological disorders.

The niche matters: origin, function and fate of CNS-associated macrophages during health and disease.

There are several cellular and acellular structural barriers associated with the brain interfaces, which include the dura, the leptomeninges, the perivascular space and the choroid plexus epithelium. Each structure is enriched by distinct myeloid populations, which mainly originate from erythromyeloid precursors (EMP) in the embryonic yolk sac and seed the CNS during embryogenesis. However, depending on the precise microanatomical environment, resident myeloid cells differ in their marker profile, turnover and the extent to which they can be replenished by blood-derived cells.

Super-Resolution Imaging to Study Co-Localization of Proteins and Synaptic Markers in Primary Neurons.

Synapses are the functional elements of neurons and their defects or losses are at the basis of several neurodegenerative and neurological disorders. Imaging studies are widely used to investigate their function and plasticity in physiological and pathological conditions. Because of their size and structure, localization studies of proteins require high-resolution imaging techniques.
