We investigated the role of DEFB1 gene (encoding for hBD-1) functional polymorphisms in the susceptibility to HIV-1 MTCT in a population from Zambia.&lt;/p&gt;&lt;p&gt;&lt;b&gt;METHODS: &lt;/b&gt;Four selected polymorphisms within DEFB1 gene, three at the 5' untranslated region (UTR), namely -52G &gt; A (rs1799946), -44C &gt; G (rs1800972) and -20G &gt; A (rs11362) and one in the 3'UTR, c.*87A &gt; G (rs1800972), were genotyped in 101 HIV-1 positive mothers (26 transmitters -27% and 75 not transmitters -73%) and 331 infants born to HIV-1 infected mothers (85 HIV-1 positive -26% and 246 exposed but not infected -74%).&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;DEFB1 c.*87-A allele was more frequent among HIV- children with respect to HIV+ (with intrauterine MTCT). Concerning DEFB1 haplotypes, GCGA haplotype resulted more represented in HIV- than HIV+ infants and DEFB1 ACGG haplotype presented increased frequency in HIV- children respect to HIV+ (with intra-partum MTCT) (p = .02, p = .002 and p = .006, respectively).&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;DEFB1 polymorphisms were significantly associated with decreased risk of HIV-1 infection acquisition in the studied Zambian population suggesting that they may play a role in HIV-1 MTCT.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/29506422?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Coelho, Antônio Victor Campos</style></author><author><style face="normal" font="default" size="100%">De Moura, Ronald Rodrigues</style></author><author><style face="normal" font="default" size="100%">da Silva, Ronaldo Celerino</style></author><author><style face="normal" font="default" size="100%">Kamada, Anselmo Jiro</style></author><author><style face="normal" font="default" size="100%">Guimarães, Rafael Lima</style></author><author><style face="normal" font="default" size="100%">Brandão, Lucas André Cavalcanti</style></author><author><style face="normal" font="default" size="100%">Coelho, Hemílio Fernandes Campos</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Meta-analysis and time series modeling allow a systematic review of primary HIV-1 drug-resistant prevalence in Latin America and Caribbean.</style></title><secondary-title><style face="normal" font="default" size="100%">Curr HIV Res</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Curr.

We also discuss whether there could be a drawback to HIV/AIDS programs due to drug resistance in Latin America and Caribbean in the next years. We observed that, although some studies report low or moderate primary drug resistance prevalence in Caribbean countries, this evidence needs to be updated. In other countries, such as Brazil and Argentina, the prevalence of drug resistance appears to be rising. Mutations conferring resistance against reverse transcriptase inhibitors were the most frequent in the analyzed populations (70% of all mutational events). HIV-1 subtype B was the most prevalent in Latin America and the Caribbean, although subtype C and B/F recombinants have significant contributions in Argentina and Brazil. Thus, we suggest that primary drug resistance in Latin America and the Caribbean could have been underestimated. Clinical monitoring should be improved to offer better therapy, reducing the risk for HIV-1 resistance emergence and spread, principally in vulnerable populations, such as men who have sex with men transmission group, sex workers and intravenous drug users.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/25777517?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kamada, Anselmo Jiro</style></author><author><style face="normal" font="default" size="100%">Pontillo, Alessandra</style></author><author><style face="normal" font="default" size="100%">Guimarães, Rafael Lima</style></author><author><style face="normal" font="default" size="100%">Loureiro, Paula</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Brandão, Lucas André Cavalcanti</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">NLRP3 polymorphism is associated with protection against human T-lymphotropic virus 1 infection.</style></title><secondary-title><style face="normal" font="default" size="100%">Mem Inst Oswaldo Cruz</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Mem.

The antiviral activity of the inflammasome cytoplasmic complex recognises viral molecular patterns and regulates immune responses via the activation of interleukin (IL)-1 family (IL-1, IL-18 and IL-33) members. The association between polymorphisms in the inflammasome receptors NLRP1 and NLRP3 and HTLV-1 infection was evaluated in a northeastern Brazilian population (84 HTLV-1 carriers and 155 healthy controls). NLRP3 rs10754558 G/G was associated with protection against HTLV-1 infection (p = 0.012; odds ratio = 0.37). rs10754558 affects NLRP3 mRNA stability; therefore, our results suggest that higher NLRP3 expression may augment first-line defences, leading to the effective protection against HTLV-1 infection.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/25411003?dopt=Abstract</style></custom1></record></records></xml>
