A commercial product with Idylle

The collaboration between the LAI (O Theodoly), the team of Tam Mignot (LCB, Marseille), and the team of Guillaume Sudre and David Laurent (IMP, Lyon) patented a process to adhere bacteria on microscope slides in 2018. The patent is now exploited by the company Idylle, and a commercial product is on the market, called “chitozen”.

Congratulations to our newest dr!

After almost 4 years with us, Farah Mustapha has successfully defended her PhD. Farah completed her work under the supervision of Pierre-Henri Puech at LAI and Kheya Sengupta at CINaM (Centre Interdisciplinaire de Nanoscience de Marseille). Throughout her PhD, she produced soft gels as a substitute for antigen presenting cells (APC) to perform traction force microscopy (TFM) experiments with the aim of investigating the role of mechanotransduction in T cell activation. 🥂

LAI welcomes its new students!

LAI welcomes the new PhD students within its fold. This year, 5 students are joining us.

Ismahene Mesbah will be working on decoding protein structural folds, sequence, and structural motifs for the mechanical stability of proteins, and Devam Purohit will be quantifying and manipulating the molecular elasticity of muscle in vitro and in vivo. Both are working at LAI and IBDM and are funded by CENTURI.

We also have Luc David-Broglio who will be developing immunological diagnostic tools that are based on antibody micro-printing and his project is funded by Région PACA, Chandrasekar Subramani-Narayana who will work between LAI and LIS and will use deep learning for image inference, resolution increase and classification of adhered immune cells and is funded by AMU, and finally, Loriane Maillot who will be working between LAI and CIML to investigate molecular dynamics of the thymic immunological synapse during leukemogenesis.

A big welcome to our new batch of students this year, and all the best on your journey!

One more Dr at LAI!

Yet another summer that ends with the graduation of a new PhD. Nicolas Garcia Seyda joined the lab as an engineer before deciding to pursue his PhD in the sunny city. He successfully defended his thesis entitled “Live imaging of leukocyte migration in controlled in vitro setups”. His presence in the lab is surely going to be missed, we wish him the best on his new adventures!

New PhDs at LAI!

LAI is happy to welcome the new batch of PhDs joining us this year.

Valentine Seveau will be using micro-fluidic techniques and micro-patterning technologies (PRIMO Alveole) to study the guidance of T cell lymphocytes mediated by integrins and cellular adhesion molecules on a substrate, also known as haptotaxis. She’ll be co-directed by Olivier Théodoly and Marie-Pierre Valignat.

Elodie Lafargue will be trying to characterize for the first time the rest structure of voltage-dependent channels at the molecular level as well as the dynamics of electrical signal transduction when opening or closing the transmembrane channel thanks to two novel breakthroughs in High-Speed Atomic Force Microscopy (HS-AFM) technology. Elodie will be supervised by Ignacio Casuso.

Rémy Torro and Lama Awada also joined us through the CENTURI PhD program. Rémy will be co-directed by Laurent Limozin at LAI and Kheya Sengupta at CINAM, he’ll be using reflection interference contrast microscopy (RICM) and deep learning-based techniques, as a systematic approach to perform 3D reconstructions of cell membranes at the interface with substrates. Lama on the other hand, is supervised by Philippe Robert at LAI and Pierre Milpied at CIML and she’ll be trying to characterize the nature of physical cues driving antibody affinity maturation in B cell immune responses using the laminar flow chamber in 2D while simultaneously integrating parallel analysis of transcriptome and antibody genes sequences at single-cell resolution.

Welcome everyone and we wish you a successful journey!

LAI welcomes new postdoc!

Dalia El Arawi started her LAI journey during COVID19 lockdown on the physical and computational aided design of bispecific antibodies for cancer immunotherapy under the supervision of Laurent Limozin. Her main objective will consist of testing bispecific antibodies using in vitro Antibody Dependent Cell Cytotoxicity mediated by NK cells employing TIRFM and RICM.
