    Insights

    Neonates with spina bifida show normal T and B lymphocyte subpopulations and mitogen responsiveness. This suggests no impairment of immune cell function in infants with this congenital condition.

    Area of Science:

    • Immunology
    • Neonatal Medicine
    • Developmental Biology

    Background:

    • Spina bifida is a complex congenital condition affecting newborns.
    • Assessing immune function in neonates with spina bifida is crucial for understanding their overall health.
    • Lymphocyte subpopulations and their responsiveness are key indicators of immune system status.

    Purpose of the Study:

    • To investigate T and B lymphocyte subpopulations in neonates with spina bifida before surgical intervention.
    • To evaluate the mitogen responsiveness of lymphocytes in these neonates.
    • To compare immune parameters between neonates with spina bifida and healthy controls.

    Main Methods:

    • Flow cytometry was used to analyze T and B lymphocyte subpopulations.
    • Phytohemagglutinin (PHA) was used as a mitogen to assess lymphocyte responsiveness.
    • Data from 15 neonates with spina bifida were compared to a control group of 30 healthy neonates.

    Main Results:

    • The mean percentage of T-lymphocytes in spina bifida patients was 44.6%, compared to 48.9% in normal neonates.
    • A normal dose response to PHA was observed in all investigated patients.
    • No significant differences were noted in B-lymphocyte subpopulations between the groups.

    Conclusions:

    • Neonates with spina bifida exhibit normal T and B lymphocyte subpopulations.
    • Lymphocyte function, as assessed by mitogen responsiveness, appears unimpaired in neonates with spina bifida.
    • These findings suggest that spina bifida does not inherently compromise early immune system development in neonates.

    Neurulation01:30

    Neurulation

    Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...

    Development of Immunocompetence

    The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
    The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
    Subsequent T...
