T cell–induced CSF1 promotes melanoma resistance to PD1 blockade

Michele De Palma, George Coukos, Krisztian Homicsko, Sina Nassiri, Natacha Anne-Sophie Bordry, Esther Danenberg, Laure Tillé, Christophe Martignier

Colony-stimulating factor 1 (CSF1) is a key regulator of monocyte/macrophage differentiation that sustains the protumorigenic functions of tumor-associated macrophages (TAMs). We show that CSF1 is expressed in human melanoma, and patients with metastatic m ...

Towards Elucidating the Mechanism of Action of Biguanides

Nicolas Peter Goeldel

Diabetes type 2 patients are insensitive to insulin, a condition that leads to reduced glucose uptake by cells and, subsequently, to high concentration of glucose in the blood. For 60 years, biguanides have been one of the few effective therapeutics in red ...

Vitamin B12 deficiency and impaired expression of amnionless during aging

Sonia Karaz, Laurence Goulet, Alice Pannerec

Background Physical frailty and loss of mobility in elderly individuals lead to reduced independence, quality of life, and increased mortality. Vitamin B12 deficiency has been linked to several age-related chronic diseases, including in the musculo-skeleta ...

Design of cyclopentadithiophene-based small organic molecules as hole selective layers for perovskite solar cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Laura Calio

Thiophene-based p-type molecules are being extensively investigated and employed in optoelectronic devices due to their intriguing semiconducting properties. Herein, we report the synthesis and characterization of a 4H-cyclopenta[1,2-b: 5,4-b']dithiophene- ...

Red blood cells ageing markers: a multi-parametric analysis

Gerardo Turcatti, Niels Erik Lion, Benjamin Rappaz, David Crettaz, Michel Prudent, Manon Sandra Bardyn

Background. Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 degrees C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells ac ...

Microdevice for Sedimentation-based Separation of Blood Microsamples at the Point of Collection

David Forchelet

Laboratory blood testing plays a central role in current diagnostics and therapeutical decisions. Thus, errors have a direct impact on care quality and cost. The majority of errors occur in the pre-analytical phase, when samples are collected, stored and p ...

Protein Corona: Impact of Lymph Versus Blood in a Complex In Vitro Environment

Heinrich Hofmann, Duncan Thomas Lindsay Alexander, Diego Chiappe, Marc Moniatte, Ulrich Aschauer, Marijana Mionic Ebersold, Débora Bonvin

In biological environments, the surface of nanoparticles (NPs) are modified by protein corona (PC) that determines their biological behavior. Unfortunately, in vitro tests still give different PC than in vivo tests causing in vitro-in vivo discrepancy; hen ...

Study of cortical energy metabolism during sensory stimulation-induced brain activity by ¹³C magnetic resonance spectroscopy in vivo

Sarah Catherine Sonnay

Cerebral function is associated with high metabolic activity that is supported by continuous supply of oxygen and glucose from the blood. Coupling between brain energy metabolism and neuronal activity has been studied extensively during the past decades. N ...

Osmolarity: A hidden factor in Nanotoxicology

Omid Mashinchian

In the field of drug delivery, long circulating nanocarriers in the blood have many advantages such as targeted drug delivery and sustained release. Based on our current knowledge, evaluation of the effect of long circulating nanocarriers in the blood stre ...

Impact of strength and size of donors on the optoelectronic properties of D-pi-A sensitizers

Mohammad Khaja Nazeeruddin, Peng Gao

A series of carbazole based sensitizers with either phenyl based donors (TBC, TMC, OMC, PC, TBR, TMR, OMR and PR) or aryl amine based donors (OMNC, CNC and HNC) as well as one without a donor group (CC) have been synthesized to understand the influence of ...
