How is clathrin recruited to the plasma membrane?
How is clathrin recruited to the plasma membrane? Clathrin-mediated endocytosis is triggered by phosphatidylinositol-4,5-bisphosphate (PIP2) accumulation within the plasma membrane. PIP2 accumulates as a result of phosphoinositide catalysis by the lipid kinases, phosphatidylinositol-4-kinase (PI4K) [...]
How does the clathrin coated pit form?
How does the clathrin coated pit form? Adaptor proteins such as AP-2, AP180 and CALM (Clathrin-assembly lymphoid myeloid leukaemia protein), which accumulate within the lipid bilayer, are responsible for the recruitment of the triskelion [...]
How does the clathrin-coated vesicle neck narrow?
How does the clathrin-coated vesicle neck narrow? In the final stages of clathrin-coated vesicle (CCV) formation, Phosphatidylinositol-4,5-bisphosphate (PIP2) undergoes a dephosphorylation by phosphatases such as synaptojanin 1 (Synj1) [1]. Not only does this inhibit [...]
How does invagination and maturation of the clathrin-coated vesicle occur?
How does invagination and maturation of the clathrin-coated vesicle occur? Clathrin-coated vesicle maturation incorporates the activities of a range of proteins. Actin, myosin and WASP all have important roles in the formation and stabilization [...]
What is flotillin-associated endocytosis?
What is flotillin-associated endocytosis? Flotillins, which are proteins that localize to specific microdomains or lipid rafts in the plasma membrane, mediate a clathrin-independent endocytosis pathway that is regulated by the Src family tyrosine kinase [...]
What is Rho-dependent IL-2 receptor endocytosis?
What is Rho-dependent IL-2 receptor endocytosis? Internalization of transmembrane receptors was thought to occur exclusively via clathrin-mediated endocytosis (CME). However, the discovery of clathrin-independent endocytic routes, in particular, the pathway that mediates the internalization [...]

Research Interests
Microfluidics, Micro-optical systems for live cell imaging
Our laboratory is primarily interested in the application of micro/nano fabrication technology to biological science. We exploit standard and advanced micro-fabrication tools in order to design and produce systems and devices for cell culturing and imaging. Examples of such devices are: topographically and/or chemically micro-textured environments, microfluidic devices, micro-optical systems and more.
We are also interested in developing microfluidic devices for FTIR spectromicroscopy of living cells. FTIR is an imaging technique that is intrinsically label-free and requires minimal sample preparation; when coupled with microscopy and high brilliance IR sources it allows the acquisition of chemical maps at a resolution which is diffraction limited. Absorption of IR photons induces very low or no damage at all, therefore it is in principle possible to observe for prolonged time the behaviour of living cells. Our research activity is intended to develope microfludic platforms suitable for FTIR (key parameters are optical transparency and low IR absorption) while keeping cells alive and healthy; a beneficial feature provided by micro-fabrication approach is the possibility to control of the chemical environment at the micro-scale.

Biography
Dr Gianluca Grenci joined MBI in 2012 as a research fellow and head of the Micro Fabrication Core facility. Previously he was employed at the LILIT micro/nano fabrication group (IOM-CNR, Trieste, IT) for a total of 6 years, during which he was mainly involved in the design and fabrication of microfluidic devices for synchrotron-light related spectroscopic techniques, such as SAXS and FTIR. He thus developed extensive practical knowledge on all the major lithographic technologies (UV and EB lithography, wet/dry etching, soft-lithography, thin films deposition), plus some less usual and/or more advanced technique, such as X-ray Lithography and LIGA.
He did his PhD in the field of applied superconductivity, in a project aimed to develop a current cryo-comparator (CCC) using high critical temperature superconductors of the cuprate family (YBCO) in the form of a thick film deposited onto a large area, complex shaped silver substrate.
