  • Antibody-Free Immunopeptide Nano-Conjugates for Brain-Targeted Drug Delivery in Glioblastoma Multiforme. bioRxiv : the preprint server for biology Sharma, S., Lee, D., Maity, S., Singh, P., Chadokiya, J., Mohaghegh, N., Hassani, A., Kim, H., Gangarade, A., Ljubimova, J. Y., Kirane, A., Holler, E. 2025

    Abstract

    Glioblastoma Multiforme (GBM) represents a significant clinical challenge amongst central nervous system (CNS) tumors, with a dismal mean survival rate of less than 8 months, a statistic that has remained largely unchanged for decades (National Brain Society, 2022). The specialized intricate anatomical features of the brain, notably the blood-brain barrier (BBB), pose significant challenges to effective therapeutic interventions, limiting the potential reach of modern advancements in immunotherapy to impact these types of tumors. This study introduces an innovative, actively targeted immunotherapeutic nanoconjugate (P12/AP-2/NCs) designed to serve as an immunotherapeutic agent capable of traversing the BBB via LRP-1 receptor-mediated transcytosis. P12/AP-2/NCs exert its immune-modulating effects by inhibiting the PD-1/PD-L1 axis through a small-size PD-L1/PD-L2 antagonist peptide Aurigene NP-12 (P12). P12/AP-2/NCs are synthesized from completely biodegradable, functionalized high molecular weight β-poly(L-malic acid) (PMLA) polymer, conjugated with P12 and Angiopep-2 (AP2) to yield P12/AP-2/NCs. Evaluating nanoconjugates for BBB permeability and 3-D tumor model efficacy using an in vitro BBB-Transwell spheroid based model demonstrating successful crossing of the BBB and internalization in brain 3D tumor environments. In addition, the nanoconjugate mediated T cell's cytotoxicity on 3D tumor region death in a U87 GBM 3-D spheroid model. AP2/P12/NCs is selectively inhibited in PD1/PDL1 interaction on T cells and tumor site, increasing inflammatory cytokine secretion and T cell proliferation. In an in-vivo murine brain environment, rhodamine fluorophore-labeled AP2/P12/NCs displayed significantly increased accumulation in the brain during 2-6 h time intervals post-injection with a prolonged bioavailability over unconjugated peptides. AP2/P12/NCs demonstrated a safety profile at both low and high doses based on major organ histopathology evaluations. Our findings introduce a novel, programmable nanoconjugate platform capable of penetrating the BBB for directed delivery of small peptides and significant immune environment modulation without utilizing antibodies, offering promise for treating challenging brain diseases like glioblastoma multiforme and beyond.

    Abstract

    Glioblastoma (GBM) is an aggressive form of cancer, comprising 80% of malignant brain tumors. However, there are no effective treatments for GBM due to its heterogeneity and the presence of the blood-brain barrier (BBB), which restricts the delivery of therapeutics to the brain. Despite in vitro models contributing to the understanding of GBM, conventional 2D models oversimplify the complex tumor microenvironment. Organ-on-a-chip (OoC) models have emerged as promising platforms that recapitulate human tissue physiology, enabling disease modeling, drug screening, and personalized medicine. There is a sudden increase in GBM-on-a-chip models that can significantly advance the knowledge of GBM etiology and revolutionize drug development by reducing animal testing and enhancing translation to the clinic. In this review, an overview of GBM-on-a-chip models and their applications is reported for drug screening and discussed current challenges and potential future directions for GBM-on-a-chip models.

  • The Utilisation of Mushroom Leftovers, Oats, and Lactose-Free Milk Powder for the Development of Geriatric Formulation. Foods (Basel, Switzerland) Paul, S., Kaushik, R., Upadhyay, S., Akhtar, A., Chawla, P., Kumar, N., Sharma, S., Rani, P. 2024; 13 (11)

    Abstract

    This study aims to focus on developing a food supplement for the geriatric population using disposal mushrooms, oats, and lactose-free milk powder. Lactose intolerance is most common in older adults, raising the demand for lactose-free foods. One of the major global challenges currently faced by humankind is food waste (FW). Most of the food that is produced for human consumption has not been utilized completely (1/3rd-1/2 unutilized), resulting in agricultural food waste. Mushrooms are highly valuable in terms of their nutritional value and medicinal properties; however, a significant percentage of mushroom leftovers are produced during mushroom production that do not meet retailers' standards (deformation of caps/stalks) and are left unattended. Oats are rich in dietary fibre beta-glucan (55% water soluble; 45% water insoluble). Lactose-free milk powder, oats, and dried mushroom leftover powder were blended in different ratios. It was observed that increasing the amount of mushroom leftover powder increases the protein content while diluting calories. The product with 15% mushroom powder and 30% oat powder showed the highest sensory scores and the lowest microbial count. The GCMS and FTIR analyses confirmed the presence of ergosterol and other functional groups. The results of the XRD analysis showed that the product with 15% mushroom powder and 30% oat powder had a less crystalline structure than the product with 5% mushroom powder and 40% oat powder and the product with 10% mushroom powder and 35% oat powder, resulting in more solubility. The ICP-OES analysis showed significant concentrations of calcium, potassium, magnesium, sodium, and zinc. The coliform count was nil for the products, and the bacterial count was below the limited range (3 × 102 cfu/g). The product with 15% mushroom powder and 30% oat powder showed the best results, so this developed product is recommended for older adults.

    Abstract

    Molecular characterization of tumors is essential to identify predictive biomarkers that inform treatment decisions and improve precision immunotherapy development and administration. However, challenges such as the heterogeneity of tumors and patient responses, limited efficacy of current biomarkers, and the predominant reliance on single-omics data, have hindered advances in accurately predicting treatment outcomes. Standard therapy generally applies a "one size fits all" approach, which not only provides ineffective or limited responses, but also an increased risk of off-target toxicities and acceleration of resistance mechanisms or adverse effects. As the development of emerging multi- and spatial-omics platforms continues to evolve, an effective tumor assessment platform providing utility in a clinical setting should i) enable high-throughput and robust screening in a variety of biological matrices, ii) provide in-depth information resolved with single to subcellular precision, and iii) improve accessibility in economical point-of-care settings. In this perspective, we explore the application of label-free Raman spectroscopy as a tumor profiling tool for precision immunotherapy. We examine how Raman spectroscopy's non-invasive, label-free approach can deepen our understanding of intricate inter- and intra-cellular interactions within the tumor-immune microenvironment. Furthermore, we discuss the analytical advances in Raman spectroscopy, highlighting its evolution to be utilized as a single "Raman-omics" approach. Lastly, we highlight the translational potential of Raman for its integration in clinical practice for safe and precise patient-centric immunotherapy.
