We report a case of a 27-year-old obese female presenting with headache, blurry and double vision. She was found to have bilateral papilledema by an ophthalmologist and sent to the emergency department (ED). Cerebrospinal fluid (CSF) analysis showed elevated opening pressure and lymphocytic pleocytosis. Symptoms improved significantly after lumbar puncture (LP). Subsequently, polymerase chain reaction (PCR) for herpes simplex virus-2 (HSV-2) came back positive. This case represents an unusual presentation of HSV-2 meningitis, where the clinical picture was suggestive of pseudotumor cerebri or idiopathic intracranial hypertension (IIH), but CSF analysis revealed HSV-2. Papilledema and elevated intracranial pressure has not previously been described in association with HSV-2. Therefore, patients presenting with typical signs and meeting all diagnostic criteria for IIH in the presence of CSF pleocytosis may represent a distinct group of viral-induced intracranial hypertension. In these cases, an investigation of viral etiologies should be conducted.

Oncolytic reprogramming of tumor microenvironment shapes CD4 T-cell memory via the IL6ra-Bcl6 axis for targeted control of glioblastoma.

Oncolytic viruses (OVs) emerge as a promising cancer immunotherapy. However, the temporal impact on tumor cells and the tumor microenvironment, and the nature of anti-tumor immunity post-therapy remain largely unclear. Here we report that CD4 T cells are required for durable tumor control in syngeneic murine models of glioblastoma multiforme after treatment with an oncolytic herpes simplex virus (oHSV) engineered to express IL-12.

The presence of hypothermia among young infants in the emergency department may be a sign of serious or invasive bacterial infections, or invasive herpes simplex viral infection. However, hypothermia may also occur due to a variety of other infectious and noninfectious conditions or environmental exposure. In some settings, hypothermia may represent a protective, energy-conserving response to illness.

CAN-2409 is a replication-defective adenovirus that delivers the herpes simplex virus (HSV)-thymidine kinase gene to infected cells. Intratumoral administration of CAN-2409 followed by prodrug results in the formation of a toxic metabolite able to induce immunogenic cell death, exposure of tumor-associated antigens, and activation of local and systemic immune responses. We used a dynamic labeling model with MC38 tumor cells implanted in photoconvertible Kaede mice.

Herpes simplex virus (HSV) infection is one of the most prevalent viral infections worldwide. In general, host immunity is sufficient to clear viral shedding and recurrences, although it is insufficient to prevent subsequent virologic reactivations. In immunocompromised patients, prolonged and difficult-to-treat HSV infections may develop.

Mucus is a complex hydrogel that acts as a defensive and protective barrier in various parts of the human body. The rise in the level of viral infections has underscored the importance of advancing research into mucus-mimicking hydrogels for the efficient design of antiviral agents. Herein, we demonstrate the gram-scale synthesis of biocompatible, lignin-based virus-binding inhibitors that reduce waste and ensure long-term availability.
