Perinatal CMV infection is common. It occurs in eight to thirteen percent of healthy newborns in the United States, and fourteen to eighteen percent of sick or premature infants.
Healthy full-term infants rarely have symptoms and are at lesser risk of long-term effects. In contrast, symptoms are common in premature and sick full-term infants and may include pneumonia, hepatitis, hemolytic anemia, thrombocytopenia, and fever. The CMV virus is closely related to the herpes group of viruses.
CMV infections can be controlled by drug therapy but, as yet, cannot be cured. Two drugs that keep the infection from getting worse are ganciclovir and foscarnet.

These are delivered intravenously, and treatment must continue over a long period of time. A tablet form of ganciclovir, approved for CMV infections of the eye, has become available. Further, ganciclovir, delivered in the form of an intravitreal implant Vitrasert Implant is available as a means of providing long-term delivery of the drug o the eye.
This delivery system requires a minor operation on the eye s in order to implant the delivery system. This form of delivery lasts for 3 to 6 months before it must be repeated. It is approved by the U. Food and Drug Administration FDA as a preventive measure prophylaxis against CMV disease associated with transplantation of the kidney, lung, liver, pancreas, and heart.

In the new study, Angulo and colleagues have investigated for the first time the immunomodulatory potential of one of these viral molecules: A43, a CD48 homolog encoded by owl monkey CMV. The researchers show that A43 binds strongly to 2B4 and is capable of blocking its interaction with CD Moreover, the findings reveal how this viral protein interferes with the function of human natural killer cells.
Cytomegalovirus (CMV) and Congenital CMV Infection
Taken together, these results not only underscore the importance of 2B4-mediated immune responses in controlling CMV infections, but also unveil CD48 as a new viral counteract mechanism for subverting immune surveillance. The authors propose that A43 may serve as a CD48 decoy receptor by binding and masking 2B4, thereby impeding effective immune control by cytotoxic lymphocytes during viral infections. According to the authors, the research highlights the potential of using the inhibitory molecule A43 to develop novel therapeutic tools to manipulate aberrant immune responses, such as those linked to autoimmune diseases.
PLoS Pathog 15 4 : e Bug of the Month helps educate readers about existing and emerging pathogens of clinical importance in healthcare facilities today. Each column explores the Bug of the Month's etiology, the infections it can cause, the modes of transmission, and ways to fight its spread. Now, a new study has investigated the origin and evolution of this virus, which may have coevolved with human lineage.
Comparing a living cell to a virus is a bit like comparing the Sistine Chapel to a backyard dog house. Lacking the intricate machinery of living cells, viruses represent biology stripped down to an extreme level.
