Nanostructured lipid carriers based mRNA vaccine leads to a T cell-inflamed tumour microenvironment favourable for improving PD-1/PD-L1 blocking therapy and long-term immunity in a cold tumour model.

Background: mRNA-based cancer vaccines show promise in triggering antitumour immune responses. To combine them with existing immunotherapies, the intratumoral immune microenvironment needs to be deeply characterised. Here, we test nanostructured lipid carriers (NLCs), the so-called Lipidots®, for delivering unmodified mRNA encoding Ovalbumin (OVA) antigen to elicit specific antitumour responses.

Temocillin efficacy against AmpC β-lactamase-producing Enterobacterales: a relevant alternative to cefepime?

Introduction: Temocillin is a semi-synthetic β-lactam with a narrow spectrum but high stability against hydrolysis by β-lactamases, including AmpC. Despite its favourable properties, data regarding its clinical value in the treatment of AmpC β-lactamase-producing Enterobacterales (ABPE) infections are scarce. Most recent guidelines do not include temocillin in the therapeutic strategy for ABPE infection.
