The pattern of inflammatory infiltration was studied in the frontal brain biopsies of 28 cases with subacute sclerosing panencephalitis (SSPE) by immunohistochemistry. Lymphocytic infiltration and gliosis were common pathologic findings. CD4+ T lymphocytes were often observed in perivascular areas and CD8+ lymphocytes in the parenchyma. B lymphocytes were located in large perivascular cuffs associated with longer and slower disease. Major histocompatibility complex antigens, interferon-gamma, and tumor necrosis factor-alpha (TNF-alpha) were expressed in endothelial and glial cells. The inflammatory lesions in subacute sclerosing panencephalitis consist of various cell subtypes and cytokines localized in particular areas of the brain tissue and show certain associations with clinical course.

Subacute sclerosing panencephalitis (SSPE) is a lethal neurological disorder occurring several years after measles. Reconstruction of the evolution of the measles virus (MeV) genome in an SSPE case suggested that the matrix (M) protein mutation M-F50S, when added to other mutations, drove neuropathogenesis. However, whether and how M-F50S would promote spread independently from other mutations was in question.

Background: Subacute Sclerosing Panencephalitis (SSPE) is a fatal disorder marked by gradual cognitive and motor deterioration, leading to death typically within 1-3 years.
Case Report: A 20-year-old woman with progressive abnormal behaviour, forgetfulness, and involuntary movements showed significant improvement after treatment with interferon and isoprinosine. Initially severely cognitively impaired and dependent, she regained independence and demonstrated marked cognitive enhancement, her MMSE improved from 15 to 28 and reduced myoclonus.

Subacute sclerosing panencephalitis (SSPE) is a devastating fatal condition caused by mutated measles virus. It predominantly affects children of younger age and invariably leads to mortality. Though reported rarely, the disease continues to cause significant morbidity in children.

During virus replication in cultured cells, copy-back defective viral genomes (cbDVGs) can arise. CbDVGs are powerful inducers of innate immune responses , but their occurrence and impact on natural infections of human hosts remain poorly defined. We asked whether cbDVGs were generated in the brain of a patient who succumbed to subacute sclerosing panencephalitis (SSPE) about 20 years after acute measles virus (MeV) infection.
