ABSTRACT
This review is a short synopsis of the roles cytokines play during fetal life, initiation
of labor, and in neonatal immunity and diseases. Hematopoietic growth factors regulate
the maturation of progenitors in fetal and neonatal hematopoietic organs. Cytokines
act as extra-hematopoietic growth factors, modulators of feto-maternal tolerance and
are involved in selective apoptosis during tissue remodeling. Inter-regulation of
cytokine networks is critical for normal function and maturation of neonatal host
defenses. Antigen specific immunity develops later in life and neonates initially
depend on natural (innate) immunity. Cytokines regulate innate immunity and connect
it with antigen specific adaptive immunity. Some cytokines have already found a place
in routine NICU therapy (EPO and G-CSF), while diagnostic and therapeutic uses of
others are under investigation (TPO, TNF-α, etc.).
