Telomere Length, HLA, and Longevity-Results from a Multicenter Study

Area of Science:

• Immunogenetics
• Gerontology
• Molecular Biology

Background:

• Longevity is influenced by genetic, environmental, and lifestyle factors.
• Previous research identified specific Human Leukocyte Antigen (HLA) haplotypes associated with longevity.
• The role of telomere length in successful aging and its connection to HLA remains to be fully elucidated.

Purpose of the Study:

• To investigate the relevance of telomere length for successful aging.
• To examine the association between telomere length and classical Human Leukocyte Antigens (HLAs).
• To identify potential immunogenetic profiles linked to longevity.

Main Methods:

• Analysis of 957 individuals from Bulgaria, Turkey, Romania, and Poland.
• Comparison between elderly (65-99 years) and young (18-64 years) age groups.
• Assessment of telomere length and Human Leukocyte Antigen (HLA) genotyping.

Main Results:

• Confirmed interpopulation differences in HLA allele distribution.
• Documented telomere lengths across the analyzed populations.
• Demonstrated significant associations between telomere length, aging, and specific HLA class I or II alleles.

Conclusions:

• Telomere length and HLA genotyping may help identify immunogenetic profiles associated with longevity.
• Observed associations between HLA and telomeres support the theory of HLA gene influence on aging.
• Further research is required to clarify the biological mechanisms underlying these relationships.
