West Nile virus (WNV) is an endemic arboviral infection in the United States that has undergone phyloge-netic evolution since its introduction 25 years ago. An integrated vector–human–pathogen study was conducted in the summer of 2023 to unearth contemporary Culex quinquefasciatus habitat patterns and human transmission spillover foci in South Carolina, a state with historically little WNV data. A serosurvey revealed WNV seroprevalence 10 times the national average (22% versus 2%, respectively), with unusual epidemiologic risk factors. Female Culex quinquefas-ciatus WNV positivity was low (2.7%), with viral phylogenetics 100% homologous to the WN02 clade. Mosquito vectors clustered in affluent urban neighborhoods …

Taming Psoriatic Inflammation: Targeting The Inos–Oxidative Stress–Necroptosis Axis For Precision Therapy, Tolulope Omotope Omolekan, Tithi Roy, Jean Christopher Chamcheu

Faculty Publications

---

Necroptosis is increasingly recognized as a central driver of psoriatic inflammation, promoting keratinocyte death and sustaining immune activation. Recent evidence shows that inducible nitric oxide synthase (iNOS) deficiency and exogenous nitric oxide (NO) supplementation ameliorate psoriasis-like dermatitis in mice by reducing oxidative stress and constraining necroptotic signaling. These findings identify iNOS-derived NO as both a mediator of reduction–oxidation (redox) imbalance and a key regulator of necroptosis, thereby advancing mechanistic insight into psoriatic pathogenesis. Importantly, they highlight the iNOS–oxidative stress–necroptosis axis as a translationally actionable therapeutic target. Modulating necroptotic cell death through NO-based interventions may restore epidermal homeostasis and improve clinical …

Myeloid cells are highly heterogeneous and play key roles in establishing an immunosuppressive tumor microenvironment (TME), but the mechanisms controlling their differentiation remain unclear. Using orthotopic murine breast cancer models, we investigated how interleukin-1α (IL-1α) influences this process. Deletion of host Il1α resulted in rejection of transplanted tumors. Single-cell RNA sequencing identified CX3CR1⁺ macrophages as the main source of IL-1α in the TME. Il1α deficiency disrupted monocyte–macrophage differentiation, reducing CX3CR1⁺ macrophages and increasing iNOS⁺ macrophages. Myeloid cells from Il1α⁻/⁻ hosts induced lower PD-1 and CTLA-4 expression in co-cultured CD8⁺ T cells than those from wild-type hosts. CellChat analysis showed …

Anoikis resistance, or evasion of cell death triggered by matrix detachment, is a hallmark of cancer cell survival and metastasis. We showed that repeated exposure to suspension stress followed by recovery under attached conditions leads to development of anoikis resistance. The acquisition of anoikis resistance was associated with enhanced invasion, chemoresistance, and immune evasion in vitro and distant metastasis in vivo. This acquired anoikis resistance was not genetic, persisting for a finite duration without detachment stress, but was sensitive to CDK8/19 mediator kinase inhibition that could also reverse anoikis resistance. Transcriptomic analysis revealed that CDK8/19 kinase inhibition induces bidirectional transcriptional …

Molecular Survival Strategies Against Kidney Filtration: Implications For Therapeutic Protein Engineering, William Heaps, Anna Elise Packard, Kristina M. Mccammon, Tyler P. Green, Joseph P. Talley, Bradley C. Bundy, Dennis Della Corte

Faculty Publications

---

The glomerular filtration barrier poses a significant challenge for circulating proteins, with molecules below ~60–70 kDa facing rapid renal clearance. Endogenous proteins have evolved sophisticated evasion mechanisms including oligomerization, carrier binding, electrostatic repulsion, and FcRn-mediated recycling. Understanding these natural strategies provides blueprints for engineering therapeutic proteins with improved pharmacokinetics. This review examines how endogenous proteins resist filtration, evaluates their application in protein engineering, and discusses clinical translation including established technologies (PEGylation, Fc-fusion) and emerging strategies (albumin-binding domains, glycoengineering). We address critical challenges of balancing half-life extension with tissue penetration, biological activity, and immunogenicity—essential considerations for the rational design of next-generation …

Aphasia severity after stroke varies widely and is not fully explained by lesion size or location. We propose that incorporating the brain’s sensorimotor-association (S-A) gradient, reflecting cortical hierarchy, offers a biologically grounded framework for predicting language outcomes. In 236 individuals with chronic left-hemisphere stroke, we examine whether the hierarchical position of lesions in language-specific (LS) and domain-general (DG) areas modulates aphasia severity. We parcellate lesions using a cortical atlas and weigh them by each region’s S-A rank. We apply hierarchical linear regression to test whether S-A ranking and its interaction with lesion volume improves prediction of Western Aphasia Battery-Revised Aphasia …

Oncolytic viruses (OVs) represent an exciting avenue in tumor immunotherapy, harnessing the power of viruses to overcome resistance and enhance immune responses. OVs achieve this by selectively targeting and destroying tumor cells. This cell lysis releases tumor-specific antigens (TAAs), effectively creating an in situ vaccine that educates the immune system. Moreover, OVs directly trigger both innate and adaptive immunity and can be genetically engineered to secrete immune-boosting factors. Early studies have shown promising synergistic antitumor effects when OVs are combined with other cancer therapies or immunotherapies. A key advantage of OVs is their capacity to reprogram the tumor microenvironment (TME), …

Imatinib mesylate (IM) and other BCR-ABL tyrosine kinase inhibitors (BCR-ABLi) are the mainstay of chronic myelogenous leukemia (CML) treatment. However, activation of circumventing signaling pathways and quiescence may limit BCR-ABLi efficacy. CDK8/19 Mediator kinases have been implicated in the emergence of non-genetic drug resistance. Dissecting the effects of pharmacological CDK8/19 inhibition on CML survival in response to BCR-ABLi, we found that a selective, non-toxic CDK8/19 inhibitor (CDK8/19i) Senexin B (SenB) and other CDK8/19i sensitized K562 cells to different BCR-ABLi via attenuation of cell cycle arrest. In particular, SenB prevented IM-induced upregulation of genes that negatively regulate cell cycle progression. SenB …
