Purpose: Metastasis to the brain from breast cancer remains a significant clinical challenge, and may be targeted with CAR-based immunotherapy. CAR design optimization for solid tumors is crucial due absence of truly restricted antigen expression potential safety concerns "on-target off-tumor" activity. Here, we have optimized HER2-CAR T cells treatment metastases, determined optimal second-generation route administration xenograft mouse models metastatic tumors, including multifocal...
An effective combination immunotherapy using oncolytic viruses delivers de novo CD19 to promote CD19-CAR T cell therapy against solid tumors in mice.
Abstract Background Timely molecular surveillance of Plasmodium falciparum kelch 13 ( k13 ) gene mutations is essential for monitoring the emergence and stemming spread artemisinin resistance. Widespread resistance, as observed in Southeast Asia, would reverse significant gains that have been made against malaria burden Africa. The purpose this study was to assess prevalence polymorphisms western Kenya Ethiopia at sites representing varying transmission intensities between 2018 2022. Methods...
Advancing chimeric antigen receptor (CAR)-engineered adoptive T cells for the treatment of solid cancers is a major focus in field immunotherapy, given impressive recent clinical responses hematological malignancies. Prostate cancer may be amenable to cell-based immunotherapy since several tumor antigens, including prostate stem-cell (PSCA), are widely over-expressed metastatic disease. While selectivity CARs crucial, it problematic due absence truly restricted expression and potential...
Abstract Background Malaria remains a significant cause of morbidity and mortality in Ethiopia with an estimated 3.8 million cases 2021 61% the population living areas at risk malaria transmission. Throughout country Plasmodium vivax falciparum are co-endemic, Duffy expression is highly heterogeneous. The public health significance negativity relation to P. Ethiopia, however, unclear. This study seeks explore prevalence rates infection across phenotypes clinical community settings. Methods A...
Piperonyl butoxide (PBO)-synergized pyrethroid products are widely available for the control of pyrethroid-resistant mosquitoes. To date, no study has examined mosquito resistance after pre-exposure to PBO and subsequent enzymatic activity when exposed PBO-synergized insecticides. We used Culex quinquefasciatus Say (Diptera: Culicidae), an important vector arboviruses lymphatic filariasis, as a model examine insecticide mechanisms mosquitoes using modified World Health Organization tube...
Advancing chimeric antigen receptor (CAR)-engineered T cells for the treatment of solid tumors is a major focus in field cellular immunotherapy. Several hurdles have hindered similar CAR cell clinical responses as seen hematological malignancies. These challenges include on-target off-tumor toxicities, which inspired efforts to optimize CARs improved tumor selectivity and overall safety. We recently developed therapy targeting prostate stem (PSCA) pancreatic cancers, showing preclinical...
Irrigated agriculture enhances food security, but it potentially promotes mosquito-borne disease transmission and affects vector intervention effectiveness. This study was conducted in the irrigated nonirrigated areas of rural Homa Bay Kisumu Counties, Kenya.We performed cross-sectional longitudinal surveys to determine Plasmodium infection prevalence, clinical malaria incidence, molecular force (molFOI), multiplicity infection. We examined impact irrigation on effectiveness new...
Abstract Chimeric antigen receptor (CAR)-engineered T cell therapy for solid tumors is limited by the lack of tumor-restricted and homogeneous expression tumor antigens 1,2 . Therefore, we engineered an oncolytic virus to express a non-signaling, truncated CD19 (CD19t) protein tumor-selective delivery, enabling targeting CD19-specific CAR cells. Infecting cells with chimeric vaccinia coding CD19t (OV19t) produced de novo surface-antigen prior virus-mediated lysis. Co-cultured CD19-CAR...
As malaria control and elimination efforts ramp up in Ethiopia, more sensitive tools for assessing exposure to coendemic Plasmodium falciparum vivax are needed accurately characterize risk epidemiology. Serological markers have been increasingly explored as cost-effective measuring transmission intensity evaluating intervention effectiveness. The objectives of this study were evaluate the efficacy a panel 10 serological proxy determine underlying factors seropositivity. We conducted...
Abstract Background Malaria remains a significant cause of morbidity and mortality in Ethiopia with an estimated 4.2 million annual cases 61% the population living areas at risk malaria transmission. Throughout country Plasmodium vivax P. falciparum are co-endemic, Duffy expression is highly heterogeneous. The public health significance negativity relation to Ethiopia, however, unclear. Methods A total 9,580 4,667 subjects from community facilities endemic site epidemic-prone western were...
