Combined Adjuvant of Poly I:C Improves Antitumor Effects of CAR-T Cells

In conclusion, CAR-T treatment combined with intratumoral delivery of poly I:C resulted in synergistic antitumor activity. We thus provide a rationale to translate this immunotherapeutic strategy to solid tumors. Introduction Adoptive T cell immunotherapy has been demonstrated to be a new way to fight malignancies. In particular, T lymphocytes engineered to express chimeric antigen receptor (CAR) have shown great promise in treating hematological malignancies (1). CD19-targeted CAR-T cells have been approved by FDA to treat relapsed B cell acute lymphoblastic leukemia (B-ALL) and Diffuse Large B-cell lymphoma (DLBCL) (2, 3). CAR-T therapy is also a novel approach to treat other malignant tumors. Currently, Glypian-3 (GPC3), epidermal growth factor receptor (EGFR), human epidermal growth factor receptor2 (HER2), carcinoembryonic antigen (CEA), disialoganglioside 2 (GD2), mesothelin, prostate-specific membrane antigen (PSMA), and interleukin-13Ra2 (IL13Ra2) have been tested as targets of CAR-T cells in solid tumor. However, CAR-T therapy for solid tumors has not been as efficient as those targeting hematologic malignancies (4–7). The reasons for the limited success of CAR T cells in solid tumor are being actively investigated, and are likely multifactorial. One major reason is the immunosuppressive microenvironment that may impede the function and persistence of CAR T cells. This includes the presence of regulatory T cells, tumor-associated macrophages, myeloid-...

We report a rare case of 74-year-old female of primary hyperparathyroidism caused by parathyroid carcinoma (PC) and coexisting multiple parathyroid adenomas. She was referred to our hospital for primary hyperparathyroidism and a suspected thyroid tumor. She had no family history of malignant tumor. Computed tomography (CT) and ultrasonography of the neck revealed some masses posterior to both thyroid lobes. Those masses were believed to be parathyroid lesions. However, another mass located posterior to the right upper thyroid lobe seemed to be heterogeneous, which indicated a malignant thyroid tumor as well as parathyroid ...

We describe a unique, complex case of a man resulted affected by both APS-2 and MEN-2a. The patient developed Hashimoto's thyroiditis, diabetes mellitus type 1 and AAD, despite testing negative for adrenal cortex autoantibodies (ACA) and steroid 21-hydroxylase autoantibodies (21-OHAb). Moreover, he had also a family history for MEN-2a and he first developed medullay thyroid cancer, then bilateral pheochromocytoma on the adrenal substrate of an AAD. On adrenal histology we found complete bilateral cortical atrophy in the presence of a lymphocytic infiltration and fibrosis, confirming an ACA and 21-OHAb-negative AAD. This da...

Conclusions: Patients with granulomatosis with polyangiitis in first years after diagnosis have higher risk of venous thromboembolism than coronary artery disease. This finding is probably related to hypercoagulability induced by the disease and its therapy. PMID: 32476955 [PubMed - in process]

We used DNA microarray and bioinformatics to interrogate gene expression profiles of tumors from apoA-I expressing (A-I Tg+/-) versus apoA-I-null (A-I KO) animals to gain insights into mechanisms of apoA-I tumor protection. Differential expression analyses of 11 distinct tumors per group with> 1.2-fold cut-off and a false discovery rate adjusted p

Authors: Miranti CK, Moore S, Kim Y, Chappeta VR, Wu K, De B, Gokhale V, Hurley LH, Reyes-Reyes EM Abstract The androgen receptor (AR) is a major driver of prostate cancer development and progression. Men who develop advanced prostate cancer often have long-term cancer control when treated with androgen-deprivation therapies (ADT). Still, their disease inevitably becomes resistant to ADT and progresses to castration-resistant prostate cancer (CRPC). ADT involves potent competitive AR antagonists and androgen synthesis inhibitors. Resistance to these types of treatments emerges, primarily through the maintenance of ...
