- AB Patterns of cytokine expression were analyzed in polyclonal and
- antigenic responses in children with perinatal HIV infection. Responses
- of PBL to PMA and A23187 calcium ionophore studied in patients in
- different stages of HIV infection revealed reduced levels of IL-2 in
- HIV-infected children beginning before 6 mo of age, and age-dependent
- increases in expression of IL-4, IL-10, and IFN-gamma. The levels of
- IL-4, IL-10, and IFN-gamma expression did not differ significantly
- between HIV-infected and age-matched uninfected children of
- HIV-seropositive mothers, except for a small reduction in HIV-infected
- children in late stages of infection. Responses to PHA, HLA
- alloantigens, HIV envelope peptides T1 and P18, and tetanus toxoid were
- studied in PBMC derived from asymptomatic and mildly symptomatic
- HIV-infected children. IL-2, IFN-gamma, IL-4, and IL-5 expression was
- detected in PHA-stimulated PBMC from all analyzed patients. HIV-infected
- children who failed to respond to HLA alloantigens, tetanus toxoid, or
- the envelope peptides had lower numbers of CD4+ cells and expressed, on
- PHA stimulation, higher levels of IL-4 and IL-5 and lower levels of IL-2
- and IFN-gamma than patients who responded to the antigenic stimulation.
- Results of these analyses suggest that cytokine expression in
- HIV-infected children depends on the character of the stimuli as well as
- the phenotype of PBMC, and indicate possible prevalence of Th2
- Ag-specific responses during the progression of HIV-induced
- immunodeficiency.
