    Insights

    Children with recurrent herpesvirus infection (RHVI) show altered blood lymphocyte metabolism, even during remission. This metabolic imbalance is linked to RHVI relapses and may persist after infection clears.

    Area of Science:

    • Immunology
    • Biochemistry
    • Pediatrics

    Context:

    • Recurrent herpesvirus infection (RHVI) is common in children.
    • Understanding the metabolic underpinnings of RHVI is crucial for managing relapses.
    • Previous research has not fully elucidated the specific metabolic alterations in lymphocytes during RHVI remission.

    Purpose:

    • To investigate the metabolic status of blood lymphocytes in children with RHVI during remission.
    • To identify specific enzymatic activities and metabolic pathways affected in RHVI patients.
    • To determine the relationship between lymphocyte metabolic profiles and the incidence of RHVI relapses.

    Summary:

    • Blood lymphocytes from healthy children and those with RHVI during remission were analyzed for NAD(P)-dependent dehydrogenase levels.
    • Patients exhibited an activated pentose phosphate pathway, increased mitochondrial oxidoreductases, and inhibited cytoplasmic NADH-dependent reactions.
    • A correlation was found between these intracellular metabolic changes and RHVI relapse frequency, with no normalization observed during remission.

    Impact:

    • Reveals persistent metabolic dysregulation in lymphocytes of children with RHVI, even in remission.
    • Suggests that lymphocyte metabolism could be a biomarker for RHVI relapse risk.
    • Opens avenues for potential therapeutic strategies targeting metabolic pathways to prevent RHVI recurrence.

    Immune Response Against Viral Pathogens

    The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
    NK Cells
    NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
    Herpes01:28

    Herpes

    Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
    Chickenpox01:20

    Chickenpox

    Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

    Genital Herpes

    Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
