Chimeric antigen receptor (CAR) technology and its application to regulatory T cells (Tregs) has garnered interest among researchers in the field of cell gene therapy. Merging benefits CAR with Tregs offers a novel promising therapeutic option for durable reshaping undesired immune responses following solid organ or hematopoietic stem transplantation, as well immune-related disorders. However, major challenges remain developing standardized robust good manufacturing practice (GMP)-compliant process CAR-Treg cells. We review current progress recommend ways improve processes based on lessons learned from first-generation Treg therapeutics anticancer CAR-T development.

Natural Killer (NK) cells and CD8+ cytotoxic T are two types of immune that can kill target through similar mechanisms. With the remarkable success chimeric antigen receptor (CAR)-engineered (CAR-T) for treating haematological malignancies, there is a rapid growing interest in developing CAR-engineered NK (CAR-NK) cancer therapy. Compared to CAR-T cells, CAR-NK could offer some significant advantages, including: (1) better safety, such as lack or minimal cytokine release syndrome neurotoxicity autologous setting graft-versus-host disease allogenic setting, (2) multiple mechanisms activating activity, (3) high feasibility 'off-the-shelf' manufacturing. be engineered diverse antigens, enhance proliferation persistence vivo, increase infiltration into solid tumours, overcome resistant tumour microenvironment, ultimately achieve an effective anti-tumour response. In this review, we focus on recent progress genetic engineering clinical application discuss current challenges future promise novel cellular immunotherapy cancer.

Chimeric antigen receptor (CAR) T cell therapy has garnered significant excitement due to its success for hematological malignancies in clinical studies leading the US Food and Drug Administration (FDA) approval of three CD19-targeted CAR products. In contrast, experience with solid tumors brain been less encouraging, only a few patients achieving complete responses. Clinical preclinical have identified multiple "roadblocks," including (1) limited array targetable antigens heterogeneous expression, (2) fitness survival before reaching tumor sites, (3) an inability cells efficiently traffic sites penetrate physical barriers, (4) immunosuppressive microenvironment.

Nucleoside-modified messenger RNA (mRNA)-lipid nanoparticles (LNPs) are the basis for first two EUA (Emergency Use Authorization) COVID-19 vaccines. The use of nucleoside-modified mRNA as a pharmacological agent opens immense opportunities therapeutic, prophylactic and diagnostic molecular interventions. In particular, mRNA-based drugs may specifically modulate immune cells, such T lymphocytes, immunotherapy oncologic, infectious other conditions. key challenge, however, is that cells notoriously resistant to transfection by exogenous mRNA. Here, we report conjugating CD4 antibody LNPs enables specific targeting interventions CD4+ including cells. After systemic injection in mice, CD4-targeted radiolabeled mRNA-LNPs accumulated spleen, providing ∼30-fold higher signal reporter isolated from spleen compared with non-targeted mRNA-LNPs.

Abstract The past decades have witnessed great progress in nanoparticle (NP)‐based brain‐targeting drug delivery systems, while their therapeutic potentials are yet to be fully exploited given that the majority of them lost during process. Rational design systems requires a deep understanding entire process along with issues they may encounter. Herein, this review first analyzes typical systemically administrated NPs‐based system and proposes six‐step CRITID cascade: circulation systemic blood, recognizing receptor on blood‐brain barrier (BBB), intracellular transport, diseased cell targeting after entering into parenchyma, internalization by cells, finally release. By dissecting six steps, seeks provide restrict efficiency as well specific requirements guarantee minimal loss at each step. Currently developed strategies used for troubleshooting these reviewed some state‐of‐the‐art features meeting highlighted. cascade can serve guideline designing more efficient systems.
