Immunopathogenesis in Chlamydia trachomatis Infected Women

Table 2

Host factors and cellular immune responses associated with susceptibility or protection from infection and/or diseases.

Host factor or responseAssociationReferences

IFN-γ production by PBMCs stimulated with Ct-hsp60Protection from incident C. trachomatis infection[34]
Low PBMC IFN-γ and high IL-10 responses to Ct-hsp60Increased risk of C. trachomatis infection and PID[7]
Low CD4 cell count in HIV-infected womenIncreased risk of PID[35]
Neutrophils and neutrophil defensin levels in cervical secretionsPositive correlation with histologic endometritis in girls with clinical PID[36]
IL-10 promoter polymorphism (IL-10-1082AA); IL-2 reductionIncreased risk of infertility[37]
Cervical cell production of IL-1β, IL-6, IL-8, and IL-10 in response to stimulation with Chlamydia trachomatis EBsPositive correlation with infertility in C. trachomatis-seropositive patients[11]
Cervical cell production of IFN-γ and IL-12 in response to stimulation with Chlamydia trachomatis EBsPositive correlation with fertility in C. trachomatis-seropositive patients[1]
