Advancements in adoptive CAR immune cell immunotherapy synergistically combined with multimodal approaches for tumor treatment

Adoptive immunotherapy,notably involving chimeric antigen receptor(CAR)-T cells,has obtained Food and Drug Administration(FDA)approval as a treatment for various hematological malignancies,demonstrating promising preclinical efficacy against cancers.However,the intricate and resource-intensive autologous cell processing,encompassing collection,expansion,engineering,isolation,and administration,hamper the efficacy of this therapeutic modality.Furthermore,conventional CAR T therapy is presently confined to addressing solid tumors due to impediments posed by physical barriers,the potential for cytokine release syndrome,and cellular exhaustion induced by the immunosuppressive and heterogeneous tumor microenvironment.Consequently,a strategic integration of adoptive immunotherapy with synergistic multimodal treatments,such as chemotherapy,radiotherapy,and vaccine therapy etc.,emerges as a pivotal approach to surmount these inherent challenges.This collaborative strategy holds the key to addressing the limitations delineated above,thereby facilitating the realization of more precise personalized therapies characterized by heightened therapeutic efficacy.Such synergistic strategy not only serves to mitigate the constraints associated with adoptive immunotherapy but also fosters enhanced clinical applicability,thereby advancing the frontiers of therapeutic precision and effectiveness.

Simultaneous wireless information and power transmission system based on a dual-frequency metasurface design

Nowadays,the number of wireless sensor devices is increasing rapidly,posing persistent challenges related to battery replacement and power wiring.This paper presents a simultaneous wireless information and power transmission(SWIPT)scheme based on a frequency diversity metasurface design,which provides a wireless power supply scheme for electrical devices such as sensors.The metasurface is designed with frequency bands commonly found in the environment,and achieves efficient absorption of electromagnetic(EM)energy at 5.8 GHz and radiation of sensor information at 2.45 GHz,making it possible to take full advantage of the energy in the environment and easy to integrate with existing systems.
