Objective:
The aim of this study was to explore the frequency of mDC and pDC and expression of surface markers of the neonates and to discuss the effect of different status of HBV infection of mother on biological characteristics of DC.
Methods:
Umbilicus cord blood in neonates of HBeAg positive HBV infected mother, HBeAg negative HBV infected mother, and normal mother were collected respectively; peripheral blood of healthy adults were selected as control group. Flow cytometry was employed to detect frequency of the mDC and its expression of CD86, frequency of pDC and its expression of CD80, CD83, CD86, and FlowJo software was used to compare these indicators among the groups.
Results:
Compared with control group, the frequency of mDC of cord blood (0.29 +/- 0.16 vs 0.81 +/- 0.17), CD86 positive rate of mDC (10.72 +/- 10.01 vs 32.13 +/- 7.46), the frequency of pDC (0.15 +/- 0.07 vs 0.30 +/- 0.07), and CD86/CD83 positive rate of pDC (31.61 +/- 12.81 vs 74.96 +/- 9.78; 42.66 +/- 20.83 vs 82.00 +/- 6.94) were lower (t = -7.86, P = 0.00; t = -5.36, P = 0.00; t = -5.43, P = 0.00; t = -8.49. P = 0.00; t = -4.90, P = 0.00).
Conclusions:
The frequency of mDC and pDC in umbilical cord blood was lower than the peripheral blood of healthy adult, which was the possible mechanism of newborns easier to chronicity after the infection of hepatitis B virus. A significant correlation was found between different status of HBV infection and costimulatory molecule CD86 positive rate of mDC, but not for the frequency of mDC and pDC, and the expression of pDC molecules.

Development of Immunocompetence
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.

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Immune Response Against Viral Pathogens
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...
