Division of Medical Oncology, University Hospital Basel, Basel, Switzerland; Laboratory of Translational Immuno-Oncology, Department of Biomedicine, University and University Hospital Basel, Basel.

We previously used a disease-specific B cell receptor (BCR) point mutation (IGLV3-21R110) for selective targeting of a high-risk subset of chronic lymphocytic leukemia (CLL) with chimeric antigen receptor (CAR) T cells. Since CLL is a disease of the elderly and a significant fraction of patients is not able to physically tolerate CAR T cell treatment, we explored bispecific antibodies as an alternative for precision targeting of this tumor mutation. Heterodimeric IgG1-based antibodies consisting of a fragment crystallizable region (Fc) attached to both an anti-IGLV3-21R110 Fab and an anti-CD3 (UCHT1) single chain variable fragment (R110-bsAb) selectively killed cell lines engineered to express high levels of the neoepitope as well as primary CLL cells using healthy donor and CLL patient-derived T cells as effectors.

Description of a patient with multiple sclerosis (MS) who underwent immunotherapy with ocrelizumab and suffered a severe course of tick-borne encephalitis (TBE): A 33-year-old man presented with acute cerebellitis with tonsillar herniation. The initial suspected diagnosis of TBE was confirmed after a significant diagnostic delay, likely caused by negative serological testing due to B-cell depletion from ocrelizumab treatment for underlying MS. TBE diagnosis was made using polymerase chain reaction (PCR) and oligo-hybrid capture metagenomic next-generation sequencing (mNGS) of cerebral spinal fluid and brain biopsy samples which yielded a near-full length TBE Virus (TBEV) genome.

Structure-Guided Engineering of a Bacterial Sesterterpene Synthase for Sesterviridene Diversification.

J Am Chem Soc

September 2025

Kekulé Institute for Organic Chemistry and Biochemistry, University of Bonn,Gerhard-Domagk-Straße 1,Bonn 53121,Germany.

Terpene synthases produce a remarkable structural diversity from acyclic precursors through complex carbocation cascades. Here, we report the crystal structure of the bacterial sesterterpene synthase StvirS bound to geranylfarnesyl thiopyrophosphate (GFSPP), revealing a preorganized active site that enforces a defined folding of the C25 backbone. Guided by this structure, active-site engineering at 11 positions yielded 23 enzyme variants and 13 new sesterterpenes.

Hypersensitivity reactions to quinolones (QHRs) have been increasing in frequency, thus classifying them as the second most frequently implicated class of antibiotics in hypersensitivity reactions (HRs). It is noteworthy that quinolones (Qs) have been observed to predominantly trigger immediate hypersensitivity reactions (IHRs). These reactions are categorized as either IgE-mediated or non-IgE-mediated, attributable to the off-target occupation of the recently described receptor, Mas-related G-protein coupled receptor member X2 (MRGPRX2), on effector cells.

Background And Aims: The large genus, Impatiens, is well known to vary excessively, presenting extensive modifications in floral structure among its 1100+ species. Phylogenetic relationships in the genus have historically been difficult to intuit based on morphology, given numerous occurrences of convergent evolution, but they are also difficult to determine based on molecular characters. In this study we focus on resolving the phylogentic relationships within the genus Impatiens, with an emphasis on continental African taxa.

Ongoing declines of large-bodied frugivores limit the dispersal of large-seeded plants, contributing to their (local) demise and 'downsizing' of seeds across assemblages. However, the extent to which human pressure leads to contemporary seed downsizing, and whether extinct megafrugivores have left imprints on seed size, remains unclear. Here, we integrate trait and distribution data for 2852 endozoochorous plant species, 48 extant and 15 extinct frugivore species across 361 assemblages on Madagascar.

Purpose: Tracer kinetic models are used in arterial spin labeling (ASL); however, deciding which model parameters to fix or fit is not always trivial. The identifiability of the resultant system of equations is useful to consider, since it will likely impact parameter uncertainty. Here, we analyze the identifiability of two-compartment models used in multi-echo (ME) blood-brain-barrier (BBB)-ASL and evaluate the reliability of the fitted water-transfer rate ).
