Published: January 2009

The molecular imprinting approach provides a unique opportunity for the creation of three-dimensional cavities with tailored recognition properties. Over the last decade this field has expanded considerably, across a variety of disciplines, leading to novel approaches and many potential applications. Progress in the field of materials science has led to significant breakthroughs and the application of the imprinting approach to novel polymeric formats offers new insights and attractive methods for the preparation of synthetic receptors. In particular, nanomaterials have received considerable attention in the developing field of nanotechnology. With a large number of recent developments in the field of molecular imprinting available, this article is focused on a selection of new systems, in particular the different formats of nanomaterials, such as nanogels, nanofibres, nanowires and nanotubes.

Roles for Prlhr/GPR10 and Npffr2/GPR74 in Feeding Responses to PrRP.

Several groups of neurons in the NTS suppress food intake, including Prlh-expressing neurons (NTS cells). Not only does the artificial activation of NTS cells decrease feeding, but also the expression of Prlh (which encodes the neuropeptide PrRP) and neurotransmission by NTS neurons contributes to the restraint of food intake and body weight, especially in animals fed a high fat diet (HFD). We used animals lacking PrRP receptors GPR10 and/or GRP74 (encoded by Prlhr and Npffr2, respectively) to determine roles for each in the restraint of food intake and body weight by the increased expression of Prlh in NTS neurons (NTS mice) and in response to the anorectic PrRP analog, p52.

In women globally, breast cancer ranks as the second most frequent cause of cancer-related deaths, making up about 25% of female cancer cases, which is pretty standard in affluent countries. Breast cancer is divided into subtypes based on aggressive, genetic and stage. The precise cause of the problem is still unknown.

Astrocytes participate in brain clearance of extracellular proteins and metabolites, through the activity of the water channel aquaporin-4 (AQP4), which can be deregulated in stress-related disorders, impairing brain waste clearance. The present study investigates the impact of dexamethasone (Dexa), a synthetic glucocorticoid used as a simplified in vitro stress model, on astrocytic AQP4 and its modulation by adenosine A receptors (AR), which blockade reverses conditions related with maladaptive stress, such as anxiety and depression. The clearance of proteins in primary astrocytic cultures, assessed using 5 kDa FITC-dextran and 45 kDa TRITC-dextran uptake, was decreased by a 24 h exposure to 100 nM Dexa.

ErbB3 is markedly overexpressed in breast cancer cells and is associated with resistance and metastasis. Additionally, ErbB3 expression levels are positively correlated with low densities of tumor-infiltrating lymphocytes, a marker of poor prognosis. Consequently, ErbB3 is a promising therapeutic target for cancer immunotherapy.

Chimeric antigen receptor (CAR) T cell therapy for solid tumors faces significant challenges, including inadequate infiltration, limited proliferation, diminished effector function of CAR T cells, and an immunosuppressive tumor microenvironment (TME). In this study, we utilized The Cancer Genome Atlas database to identify key chemokines (CCL4, CCL5, and CCR5) associated with T cell infiltration across various solid tumor types. The CCL4/CCL5-CCR5 axis emerged as significantly correlated with the presence of T cells within tumors, and enhancing the expression of CCR5 in CAR T cells bolstered their migratory capacity.
