Broadly Applicable Bispecific Linker Approach to Noncovalently Target Therapeutic Nanoparticles to Tumor Cells Expressing Carcinoembryonic Antigen.

Design strategies that lead to a more focused in vivo delivery of functionalized nanoparticles (NPs) and their cargo can potentially maximize their therapeutic efficiency while reducing systemic effects, broadening their clinical applications. Here, we report the development of a noncovalent labeling approach where immunoglobulin G (IgG)-decorated NPs can be directed to a cancer cell using a simple, linear bispecific protein adaptor, termed MFE23-ZZ. MFE23-ZZ was created by fusing a single-chain fragment variable domain, termed MFE23, recognizing carcinoembryonic antigen (CEA) expressed on tumor cells, to a small protein ZZ module, which binds to the Fc fragment of IgG.

Development of a Cat Behaviour Issues Assessment Scale (CABIAS) Assessing Problem Behaviours in Cats.

Problem behaviours in cats, such as urine marking, scratching, fear, and problems of cohabitation between cats, can present a potential welfare problem for those affected cats and have a negative impact on the human-animal bond. The aim of this study was to develop a Cat Behaviour Issues Assessment Scale (CABIAS) for caregivers to assess these common problem behaviours in cats, and to investigate aspects of the validity and reliability of the CABIAS. The CABIAS uses an index score as a scoring system combining aspects of the frequency and intensity of the problem behaviour.

The IgV domain of the poliovirus receptor alone is immunosuppressive and binds to its receptors with comparable affinity.

PVR (poliovirus receptor) functions as a ligand that signals through TIGIT and CD96 to induce suppression of T-cell and NK-cell responses. Alternatively, PVR binds to CD226, resulting in a co-stimulatory signal. To date, TIGIT antibody antagonists have been developed to restore immune functions and allow PVR to signal though CD226 in the context of cancer immunotherapy.

Development of a Positive Psychology Well-Being Intervention in a Community Pharmacy Setting.

: Community pharmacies are well-placed to deliver well-being interventions; however, to date, nothing has been produced specifically for this setting. The aim of this study was to develop a positive psychology intervention suitable for a community pharmacy setting with the goal of increasing the well-being of community members. : Intervention development consisted of three steps: Step 1-identify the evidence-base and well-being model to underpin the basis of the intervention (Version 1); Step 2-model the intervention and gather user feedback to produce Version 2, and Step 3-revisit the evidence-base and refine the intervention to produce Version 3.

VISTA as a ligand downregulates LPS-mediated inflammation in macrophages and neutrophils.

VISTA has been proposed to function both as a ligand and a receptor to dampen immune responses, although the role of VISTA as a ligand on myeloid cells has been largely ignored. We observed that a VISTA receptor is rapidly expressed on the surface of macrophages and neutrophils upon exposure to lipopolysaccharides (LPS). Importantly, treating LPS-stimulated macrophages and neutrophils ex vivo with a high-avidity agonist of the VISTA receptor (VISTA.
