It is well recognized that plaque microbiota alone cannot account for periodontal tissue destruction, as some individuals are relatively at a higher risk for tissue destruction than others. Probably, some host factors have a role to play in this field. It is well documented that the human leukocyte antigens (HLA) system is a complex genetic polymorphic system in man. HLA have been considered a candidate of genetic risk markers for aggressive periodontitis (AP). The HLA play an important role in immune responsiveness and may be involved in antigen recognition of periodontal pathogens. These cell surface molecules have a key role in antigen presentation and activation of T-cells. The polymorphisms of HLA can directly affect the binding capability of antigen peptides and thus affect the antigen-specific T-cell response. Hence, these polymorphisms could represent an important susceptibility or resistance factor to periodontitis.

| Introduction|| |
Human periodontitis is a multifactorial disease, consist of a varied group of infectious diseases characterized by the complex host-microorganism infections in periodontium. Periodontal disease may differ regarding bacterial etiology, host response, and disease progression. These evidences suggest that underlying host susceptibility factors play an important role in disease progression. Immunogenic mechanisms determine individual host susceptibility, which results in the progression of periodontitis. Due to the presence of numerous genetic factors, the importance of various human leukocyte antigen (HLA) markers have been investigated in many studies. It has been evaluated to determine individual susceptibility factors in aggressive forms of periodontitis and adult periodontitis. HLA are present on the surface of leukocytes and set of genes coding them are called as HLA complex. The HLA complex genes are present on the short arm of chromosome 6. Recognition of antigen peptides and their presentation to T-cells is important for an immune response toward periodontal pathogens. Because of the presence of antigen and activity of T-cell is prevented by the major histocompatibility complex (MHC). MHC in humans is known as HLA.
Therefore the purpose of the review is to illustrate the role of HLA in periodontal disease and also to clarify how the diversity of HLA types affects periodontal disease.
| Types of Human Leukocyte Antigen|| |
- Class I-HLA (A, B, C), generally for cellular immune response
- Class II– HLA D, DR, DQ, DP, needed to mount a humoral immune response
- Class III– activate complement system.
| Mechanism of Action|| |
HLA have been known as “antigens for tissue adaptation,” means they play a role in the immune reaction. They work by presenting foreign or nonself-antigens to immune cells such as helper T-cells. After nonspecific defense by neutrophils, the bacteria are phagocytized and digested by monocytes/macrophages, and presented to helper T-cells. This binding capability depends on the amino acid sequence of the variable domains of the HLA molecule, which is specific to the HLA type. After this event, helper T-cells are activated and mediate the further steps in the immune reaction. Therefore, the HLA molecule has an important role in initiating specific immune responses in infectious diseases.
| Human Leukocyte Antigens Serotypes Associated with Periodontal Diseases|| |
Since Terasaki et al. established the HLA serotyping method in 1975 on the association of HLA serotypes with periodontal diseases. Most of these studies dealt with the HLA class I molecule, which is involved in cellular immunity. Some studies found no obvious correlation between any HLA types and periodontal disease.
| Aggressive Periodontitis|| |
Terasaki et al. 1975 and Kaslick et al. 1980 in their study evaluated the decrease number of HLA-A2 in juvenile periodontitis patients. Tiwari and Terasaki et al. 1985, analyzed the juvenile periodontitis, and stated that only B15 was responsible. Klouda et al. 1986, examined 44 patients and observed that there was an increased in frequency of HLA-A9 in rapidly progressive patients. Katz et al. 1987 reported the role of DR4 with rapidly progressive periodontitis in Jewish population subjects. The authors concluded that 80% of the patients were effective for HLA-DR4 compared to the control group. Shapira et al. 1994 observed A9 and B15 were associated with generalized early-onset periodontitis, but not with localized type of disease. Firatli et al. 1996 found HLAs A24, A9 and DR4 were associated with Juvenile and rapidly progressive periodontitis.
| Chronic Periodontitis|| |
Goteiner and Goldman 1984 observed decreased frequency of HLA-B5 in chronic adult periodontitis. Also found that there is an increased frequency of HLA-A9,-B15 and-A29 (A19) and a decreased occurrence of HLA-A2, A3 and-B5 in chronic periodontitis.
| Human Leukocyte Antigens Genotypes Associated with Periodontal Diseases|| |
Since serological HLA types include many subtypes, it may have been difficult to isolate specific serotypes. To distinguish the differences precisely, HLA typing is now performed at the gene level. Several researchers have tried to find links between HLA genotypes and periodontal diseases. Overall, however, there are few reports describing this correlation, suggesting the difficulty involved in that type of study with the technology available.
| Genotyping not Specific to Human Leukocyte Antigens Type|| |
There has been one attempt to find a genotype not directly specific to HLA types. An atypical restriction fragment length polymorphism (RFLP) pattern was found in the HLA-DQBl gene that encodes the highly polymorphic β-chain of the HLA-DQ molecule Takashiba et al. 1999. The genomic DNA is digested with the restriction enzyme, and DNA fragment is detected by Southern hybridization with the cDNA probe. An uncommon pattern with DNA fragments was found by RFLP analysis of DNA isolated from periodontitis patients which was confirmed by nucleotide sequencing. This atypical site was found in EOP patients than adult periodontitis (AP) patients or in healthy controls.
| Genotyping Specific to Human Leukocyte Antigens Type|| |
For HLA type-specific genotyping is the group-specific polymerase chain reaction (PCR)-RFLP method established by Ota et al. After gene amplification of the polymorphic region in the second exon of HLA-DRBl,-DQAl and-DQBl by PCR, the amplified DNA fragment was digested with group-specific restriction enzymes. Studies by Ohyama et al. 1996 showed that the HLA-DRB1 * 14O1 and * I501, HLA-DQA*0101, and HLA-DQB1*O5O3 and * 0602 genotypes were detected in EOP patients with elevated relative risk). However, none of the genotypes associated significantly with the disease in this study. In another study, Bonfil et al. observed DRB1 * 0401, *0404, *0405 and * 0408 in severe forms of periodontal disease and in rapidly progressive periodontitis by PCR-allele-specific oligonucleotide method in a case-control study.
Recently, studies have been carried out to determine the function of HLA genotypes associated with periodontal disease in diabetic patients and indirectly evaluated immune reactions to the HLA types isolated. The direct immunological functions such as T cell proliferation specific to HLA types were also investigated (Ohyama et al. 1996).,,,,,
| Summary|| |
Research in HLA genetics has improved remarkably in recent years to contribute to the diagnosis of susceptibility to aggressive forms of periodontitis and to our understanding of its role in pathogenesis. Host antigens homologous to the T cell epitopes of antigenic proteins of periodontal bacteria and antigens of other periodontal bacteria should be studied further.
