Impact of Sequential Ramucirumab Plus Docetaxel After PD‐1 Inhibitors on Anti‐PD‐1 Antibody‐Bound T‐Cell Dynamics and Clinical Outcomes

Cancer Science, Volume 117, Issue 4, Page 929-942, April 2026.
Ramucirumab (RAM) plus docetaxel (DOC) after PD‐1 inhibitors showed clinical activity, with responders exhibiting maintained anti–PD‐1 (IgG4+)‐bound CD8+ T cells and decreased IgG4+ Tregs. A sequential strategy of administering RAM plus DOC during persistent anti–PD‐1 antibody binding may be beneficial in patients with advanced non‐small cell lung ...

A Review of the Scale and Sustainability of the Consumption and Trade of Anuran Species in Africa

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Within Africa, collection and trade of anurans is often recorded as single‐site case studies, making it difficult to accurately understand the scale of use, its livelihood importance, and impact on species. We conducted a systematic review to: compile literature on anuran uses in Africa; identify the species and ecoregions involved; and ...
