MHCII-disease association is not restricted to structural variation alone but also may extend to genetic variations, which may modulate gene expression. The observed variations in class II gene expression make it possible that the association of MHCII polymorphism with diseases may relate to the level of gene expression in addition to the restriction of response to Ag. Understanding the extent of, and the mechanisms underlying, transcription factor DNA binding variation is therefore key to elucidate the molecular determinants of complex phenotypes. In this study, we investigated whether single nucleotide polymorphisms in MHCII-DRB regulatory gene may be associated with clinical outcomes of malaria in Plasmodium-infected individuals. To this end, we conducted a case-control study to compare patients who had mild malaria with those patients who had asymptomatic Plasmodium infection. It demonstrates that GTAT haplotype exerts an increased DRB transcriptional activity, resulting in higher DRB expression and subsequently perturbed Ag presentation and T cell activation, higher TLR-mediated innate immune gene expression, and Ag clearance, so low parasitemia in comparison with haplotypes other than GTAT (GTAC, GGGT). Hence, we hypothesized that DRB gene promoter polymorphism might lead to altered DRB gene expression, which could possibly affect the TLR-triggered innate immune responses in malaria patients. These genetic findings may contribute to the understanding of the pathogenesis of malaria and will facilitate the rational vaccine design for malaria.<\/jats:p>","DOI":"10.4049\/jimmunol.1900558","type":"journal-article","created":{"date-parts":[[2020,1,15]],"date-time":"2020-01-15T18:54:18Z","timestamp":1579114458000},"page":"943-953","source":"Crossref","is-referenced-by-count":1,"title":["MHC Class II (DRB) Promoter Polymorphism and Its Role in Parasite Control among Malaria Patients"],"prefix":"10.1093","volume":"204","author":[{"given":"Pranati","family":"Sar","sequence":"first","affiliation":[{"name":"Institute of Science, Nirma University , Ahmedabad ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aarushi","family":"Agarwal","sequence":"additional","affiliation":[{"name":"Institute of Science, Nirma University , Ahmedabad ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Devansi Hansrajbhai","family":"Vadodariya","sequence":"additional","affiliation":[{"name":"Institute of Science, Nirma University , Ahmedabad ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiral","family":"Kariya","sequence":"additional","affiliation":[{"name":"Institute of Science, Nirma University , Ahmedabad ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaydipbhai","family":"Khuman","sequence":"additional","affiliation":[{"name":"Institute of Science, Nirma University , Ahmedabad ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1466-4265","authenticated-orcid":false,"given":"Sarat","family":"Dalai","sequence":"additional","affiliation":[{"name":"Institute of Science, Nirma University , Ahmedabad ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,2,15]]},"reference":[{"key":"2025030417510764700_r1","doi-asserted-by":"crossref","first-page":"685","DOI":"10.1038\/ni1088","article-title":"The exogenous pathway for antigen presentation on major histocompatibility complex class II and CD1 molecules","volume":"5","author":"Watts","year":"2004","journal-title":"Nat.
