The Lasiocampidae (Lepidoptera: Lasiocampoidea) of Maputo Special Reserve, Mozambique: a provisional checklist with descriptions of three new species and taxonomic notes.

A preliminary checklist of 39 species of lappet moths (Lasiocampidae) is provided for Maputo Special Reserve in southern Mozambique of which three are new to science, Diapalpus smithi sp. n., Eutricha giustii sp.

Optimizing Siglec-8-Directed Immunotherapy for Eosinophilic and Mast Cell Disorders.

Current treatments for eosinophilic and mast cell disorders are often ineffective. One promising target to improve outcomes is sialic acid-binding immunoglobulin-like lectin-8 (Siglec-8). As limitations, there are few Siglec-8 monoclonal antibodies (mAbs) available to date, and Siglec-8-directed treatments have so far primarily focused on unconjugated mAbs, which may be inadequate, especially against mast cells.

Targeting the membrane-proximal C2-set domain of CD33 for improved CAR T cell therapy.

Current CD33-targeted immunotherapies typically recognize the membrane-distal V-set domain of CD33. Here, we show that decreasing the distance between T cell and leukemia cell membrane increases the efficacy of CD33 chimeric antigen receptor (CAR) T cells. We therefore generated and optimized second-generation CAR constructs containing single-chain variable fragments from antibodies raised against the membrane-proximal C2-set domain, which bind CD33 regardless of whether the V-set domain is present (CD33 antibodies).

Preclinical Characterization of the Anti-Leukemia Activity of the CD33/CD16a/NKG2D Immune-Modulating TriNKET CC-96191.

Increasing efforts are focusing on natural killer (NK) cell immunotherapies for AML. Here, we characterized CC-96191, a novel CD33/CD16a/NKG2D immune-modulating TriNKET. CC-96191 simultaneously binds CD33, NKG2D, and CD16a, with NKG2D and CD16a co-engagement increasing the avidity for, and activation of, NK cells.
