The utilization of the human immune system as a therapeutic modality has materialized in the form of novel biologics known as immune effector cells (IECs). However, currently approved IECs rely on autologous cells for manufacturing that are funneled through costly centralized supply chains leading to long wait times and potentially increased mortality. Alternative models for manufacturing at or near the point-of-care in a distributed and local approach are being proposed to overcome such a bottleneck. Cell processing facilities for minimally manipulated products, as well as academic good manufacturing practice facilities, are being considered for such manufacturing tasks. However, the infrastructure and the practices of these facilities remains unstudied. Here, we surveyed the cell processing facilities accredited by the Foundation for Accreditation of Cellular Therapy (FACT) in the United States to better understand their preparedness for local manufacturing of IECs. A structured survey consisting of 40 items was distributed to the directors of 157 facilities. The survey evaluated 6 domains, including facility characteristics, quality practices, personnel, use of automation, experience with IECs, and the perception of the point-of-care model. Thirty-eight facilities completed the survey (24.2%). Most facilities were involved in handling IEC products (35/38, 92.1%), and the majority had infrastructure to support basic operations and quality control such as viability (36/36, 100%), identity (33/36, 91.7%), and sterility (33/36, 91.7%). The quality practices varied among the facilities depending on the types of products processed. A slight majority implemented automation in their workflows (22/38, 57.9%). Facilities expressed a general interest in adopting point-of-care models (23/38, 61%), with financial and human resources identified as the most significant constraints. In conclusion, FACT-accredited cell processing facilities may provide the infrastructure required for local manufacturing. However, there is a need for standardization and minimum quality requirements to effectively implement such models.

Background: PPM1D (protein phosphatase Mg⁺/Mn⁺ dependent 1D) is a Ser/Thr phosphatase that negatively regulates p53 and functions as an oncogenic driver. Its gene amplification and overexpression are frequently observed in various malignancies and disruption of PPM1D degradation has also been reported as a cause of cancer progression. However, the precise mechanisms regulating PPM1D stability remain to be elucidated.

Oncometabolites are aberrant metabolic byproducts that arise from mutations in enzymes of the tricarboxylic acid (TCA) cycle or related metabolic pathways and play central roles in tumor progression and immune evasion. Among these, 2-hydroxyglutarate (2-HG), succinate, and fumarate are the most well-characterized, acting as competitive inhibitors of α-ketoglutarate-dependent dioxygenases to alter DNA and histone methylation, cellular differentiation, and hypoxia signaling. More recently, itaconate, an immunometabolite predominantly produced by activated macrophages, has been recognized for its dual roles in modulating inflammation and tumor immunity.

Purpose: Lung cancer is currently the most common malignant tumor worldwide and one of the leading causes of cancer-related deaths, posing a serious threat to human health. MicroRNAs (miRNAs) are a class of endogenous non-coding small RNA molecules that regulate gene expression and are involved in various biological processes associated with lung cancer. Understanding the mechanisms of lung carcinogenesis and detecting disease biomarkers may enable early diagnosis of lung cancer.

Mixed neuroendocrine and non-neuroendocrine neoplasms (MiNEN) represent a heterogeneous group of bidirectionally differentiated epithelial malignancies that are, in most cases, highly aggressive. They are defined by the presence of morphologically distinct, yet clonally related, neuroendocrine and non-neuroendocrine components, each comprising at least 30% of the tumor mass according to current guidelines. Tumors that fall within the differential diagnostic spectrum of MiNEN include amphicrine carcinomas-characterized by the co-expression of neuroendocrine and non-neuroendocrine features within the same tumor cell-as well as conventional carcinomas that lack neuroendocrine morphology but exhibit immunohistochemical expression of neuroendocrine markers.

Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma with a poor prognosis and short survival rates. It is classified as a large B-cell lymphoma subtype, but carries a plasmacytic immunophenotype. Therefore, PBL has pathogenetic overlaps with diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS) and plasma cell neoplasms (PCNs).
