Immune checkpoint inhibitors (ICIs) are an effective immunotherapeutic approach for cancers affecting the lung, skin, kidney, mammary gland, or certain hematologic malignancies. Regarding the prognosis of these oncological conditions, treatments with ICIs open new therapeutic perspectives with benefits for both patients and healthcare providers. A drawback of immune checkpoint inhibition is the occurrence of immune-related adverse events that can involve a wide range of organs, such as the liver. Given widespread usage of immunotherapy, the number of patients who suffer from this unwanted condition has increased. Hepatopathy induced by ICIs can be severe and can even lead to death. Detecting …

Il-7rα On Cd4+ T Cells Is Required For Their Survival And The Pathogenesis Of Experimental Autoimmune Encephalomyelitis, Gholamreza Azizi, Bram Van Den Broek, Larissa Ishikawa, Hamed Naziri, Reza Yazdani, Guang-Xian Zhang, Bogoljub Ciric, Mohamad Rostami

Department of Neurology Faculty Papers

BACKGROUND: The IL-7 receptor alpha (IL-7Rα) binds both IL-7 and thymic stromal lymphopoietin (TSLP). IL-7Rα is essential for the development and survival of naive CD4+ T cells and their differentiation to effector/memory CD4+ T cells. Mice lacking IL-7Rα have severe lymphopenia and are resistant to experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis. However, it has been reported that IL-7Rα on peripheral CD4+ T cells is disposable for their maintenance and EAE pathogenesis, which does not align with the body of knowledge on the role of IL-7Rα in the biology of CD4+ T cells. Given that a definitive study …

Research Colloquium

Pancreatic ductal adenocarcinoma is the third leading cause of cancer-related deaths in the United States with limited therapeutic options available. Gemcitabine, a deoxycytidine nucleoside analog is currently considered the most effective therapy for PanCa. However, it shows only a marginal survival benefit of six months. Aberrant ribosome biogenesis occurs in most tumor types. We observed that PanCa cells are addicted to ribosome biogenesis, which supports their highly aggressive metastatic phenotypes. Thus, strategically targeting ribosome biogenesis process could be one of the ideal strategies for the prevention and treatment of PanCa. In this study, we elucidated the molecular mechanisms of POLR1A …

Mouse Monocytes Express Cd127 By Immune Cells, Not Lps, Reza Yazdani, Mozhde Askari, Amir Moghadam-Ahmadi, Gholamreza Azizi, Bogoljub Ciric, Alexandra Boehm, Guang-Xian Zhang, Mohamad Rostami

Department of Neurology Faculty Papers

The essential role of interleukin 7 (IL-7) signaling via its receptor (IL-7Rα; CD127) in T cell development and function has been well documented. However, CD127 expression and function in myeloid cells, including monocytes, are less clear, especially in mice. In the present study we report an inducible CD127 expression in mouse monocytes/macrophages. This induction is dependent on the presence of other immune cells, highlighting that regulation of CD127 expression on monocytes differs in mice and humans. We demonstrate that CD127 is functional, as IL-7 downregulated its expression. We also saw decreased CD127 expression during inflammation in vivo. Overall, upregulation …

Successful Treatment Of A Chronic Recurrent Expanding Hematoma Of The Thigh, Gianfranco Galantini, Bakhtawar Mushtaq, Jesse Ottaway, Charles Long

Abington Jefferson Health Papers

Chronic expanding hematoma (CEH) is a rare entity that poses diagnostic and therapeutic challenges due to persistent growth, risk of recurrence, and potential for blood loss anemia. The most common etiologies of CEH are trauma or surgery. It is thought to occur due to irritant effects of blood breakdown products, causing bleeding from capillaries in chronic granulation tissue. Although treatment of CEH is variable, complete surgical excision of the hematoma and its pseudocapsule is the gold standard. We present a case of a 15-year CEH that was initially treated with limited evacuation of the hematoma and cavity decortication, resulting in …

Radiolabeled antibodies have become indispensable tools in nuclear medicine. However, the natural roles of antibodies within the immune system mean that they have several intrinsic limitations as a platform for radiopharmaceuticals. A handful of recent preclinical studies suggest that binding by FcR and particularly FcyRI can affect the pharmacokinetic profiles of 89Zr-labeled radioimmunoconjugates. Fc receptors (FcR) are responsible for many of the interactions between immunoglobulins (IgG) and immune cells. In biomedicine, this interplay is critical to the activity of several types of immunotherapeutics; however, relatively little is known about how FcRs affect the in vivo performance of radiolabeled antibodies. Antibodies …
