Objectives:Toll-like receptors (TLRs) play an important role in the innate immune response to pathogens. TLR7 recognizes RNA of various viruses including HIV. The objective of this study was to examine the influence of individual genetic variations of TLR7 on the susceptibility to and progression of HIV disease. Method:We genotyped a population of 734 HIV-positive adults and 545 healthy controls for three TLR7 single nucleotide polymorphisms. The frequency of TLR7 genetic variations was… 
Effects of TLR7 Polymorphisms on the Susceptibility and Progression of HIV-1 Infection in Chinese MSM Population
TLDR
A role for genetic variations of TLR7 in susceptibility and disease progression of an HIV-1 infection in Chinese Han population is supported and warrants further studies on the effect ofTLR7 polymorphisms on HIV- 1 infection in different populations.
Toll-like receptor polymorphism associations with HIV-1 outcomes among sub-Saharan Africans.
TLDR
TLR SNPs impact HIV-1 outcomes with epidemiologic factors modifying these relationships, and TLR7 rs179012 andTLR2 597C/T reduced set-point; the latter modified by time since HIV- 1 acquisition.
Association of toll-like receptor polymorphisms with HIV status in North Americans
TLDR
This study provides in-depth insight into the associations between TLR variants, particularly TLR1 and TLR6, and HIV status in North Americans, and suggests that these associations may be race specific.
Host genetic polymorphisms associated with innate immune factors and HIV-1.
TLDR
Genetic and functional data confirm the importance of KIR-HLA interactions and provide new understanding of the role of innate restriction factors in resistance to HIV-1 and disease progression.
Polymorphisms of Toll-Like Receptors and Their Pathways in Viral Hepatitis
TLDR
There is now significant evidence that a number of TLR SNPs can affect various clinical outcomes in Caucasian patients with chronic HCV, and their influence requires further investigation to determine the clinical significance of genetic variations in these mediators.
Genetic and Functional Characterization of Toll-Like Receptor Responses in Immunocompetent Patients With CMV Mononucleosis
TLDR
TLR-mediated responses in CMV-infected patients appeared to be skewed toward a pro-inflammatory profile, which may contribute to the development of inflammatory symptoms during the CMV mononucleotic syndrome.
Toll‐like receptor polymorphism in host immune response to infectious diseases: A review
TLDR
Molecular studies on polymorphic residues present in the nucleotide or in the amino acid sequence of Toll‐like receptors can improve the understanding on the genetic basis of the immune response and pave the way for therapeutic intervention in a more feasible way.

A functional toll-like receptor 8 variant is associated with HIV disease restriction.
TLDR
This first report of a functional TLR8 variant associated with a different clinical course of an RNA viral disease may have implications for the individual risk assessment of patients infected with HIV and other RNA viruses as well as for future HIV vaccine development.
Polymorphisms in Toll-like receptor 9 influence the clinical course of HIV-1 infection
TLDR
Rapid progression of HIV-1 infection was associated with TLR9 polymorphisms, and this association has potential implications for intervention strategies and vaccine developments.
Toll-like receptor (TLR) polymorphisms in African children: common TLR-4 variants predispose to severe malaria.
TLDR
TLR4-mediated responses to malaria in vivo and TLR-4 polymorphisms to be associated with disease manifestation are suggested, however some gray areas also suggest the scope for further improvements.
Association of TLR7 single nucleotide polymorphisms with chronic HCV‐infection and response to interferon‐a‐based therapy
TLDR
The results suggest that variations of TLR7 impair the immune response to HCV and imply a gender‐specific effect of this X‐chromosomal variation.

Toll-like receptors (TLRs) and members of their signaling pathway are important in the initiation of the innate immune response to a wide variety of pathogens. The adaptor protein Mal (also known as
MyD88-Dependent Immune Activation Mediated by Human Immunodeficiency Virus Type 1-Encoded Toll-Like Receptor Ligands
TLDR
It is demonstrated that the single-stranded RNA of HIV-1 encodes multiple uridine-rich Toll-like receptor 7/8 (TLR7/8) ligands that induce strong MyD88-dependent plasmacytoid dendritic cell and monocyte activation, as well as accessory cell-dependent T-cell activation, which suggests a direct contribution ofAIDS-1 itself to immune activation.

TLDR
Any effect of TRIM5α polymorphism on HIV-1 infection in primary lymphocytes may depend on combinations of SNPs or on DNA sequences in linkage disequilibrium with the TRim5α coding sequence.
