Allele frequencies and disease susceptibility. Genotyping for the CCR5-Δ32 mutation was successfully performed on all patients and controls. None of the patients and only two of the controls were ...

Adding to his sins, He knew after the gene editing — but before the embryos were transferred to their mother’s uterus — that one of the twins, whom he called Lulu, had a normal CCR5 allele ...

Recent epidemiological data and projections indicate that HIV infection will spread rapidly in India. An allele Δccr5 of the β-chemokine receptor gene CCR5 has been found to confer protection ...

The identified CCR5 allele carries a deletion (delta 32) that seems to inactivate the receptor. As chemokines signal through their receptors and influence T-cell migration, a defect in one of the ...

Those “multiple fronts” included a poor understanding of how the absence of the CCR5 gene might affect Asian individuals, particularly the way in which the introduced allele, or mutated gene ...

Individuals homozygous for the CCR5 gene Δ32 allele appear to naturally resist infection with CCR5-tropic HIV strains (R5) because they lack cell surface expression of CCR5. Stem Cell Transplant ...

CCR5 is the most commonly used receptor by HIV-1. People who have two mutated copies of the CCR5 allele are resistant to the HIV-1 virus strain that uses this receptor, as the virus cannot enter ...

Nature is complicated, viruses are tricky, assumptions are dangerous — and He Jiankui's CRISPR experiment on human embryos was, amazingly, even worse than I first thought.

In 1996, researchers discovered that CCR5 encodes a receptor on CD4+ cells that HIV uses to enter the cells early on during an infection. People who have two copies of the so-called Δ32 allele don’t ...

And still more questions surround the genetic surgery Dr. Jiankui’s team performed, which do not conclusively show (at least in one case) that the desired effect—a null CCR5 allele—has been ...

In addition to chemotherapy, he underwent a haematopoietic stem cell transplant from a donor with two copies of the CCR5 Δ32 allele in 2016. CCR5 is the most commonly used receptor by HIV-1.
