‘Natural Killer’ Tapped into T cells During Tumor Growth Process

Private laboratories have successfully acquired cells capable of attacking and replicating the human immunodeficiency virus (HIV) while carrying harmless properties, scientists said on Monday.

The research by scientists at the University of California, Irvine was presented at the 2019 Experimental Biology conference in Austin, Texas, and included testing of the stem cells in wealthy communities in the United States. Stage IV tests on such cells indicate viability, meaning no further activity.

Federal health officials in West Virginia have seen vulnerabilities in acquiring immune subsets from individuals that have contracted the plague, for example.

“In West Virginia, we have a 5-year epidemic now in which an HIV epidemic is circulating. Current strategies are limited, but in the future it could be observed to be vaccine-resistant,” said Monica Mengford, an expert on HIV/AIDS and immunocapsid targeting in HIV/AIDS-uninfected patients.

Aims to retrained the natural killer technology include editing the mother’s immune cells with a similar modification such as penicillin-1, thereby “testing” whether the cells can replicate.

The next step, he said, is to be able to train the daughter cells to become responders as well.

Intraderzation uses viruses to infect cells in response to tissue damage. Researchers say the use of natural killer cells is not necessary, saying their model can pass a broad immune control. It can also identify, at least in selected instances, patients who are at risk of developing resistance to killable pathogens.

The aim of the current extracellular life form experiment was to test different cellular models, said Dr. Q. Richard Lu, one of the co-first authors and a virology researcher from the University of South Carolina.

“Over time it becomes a natural hit-and-kill type of immune response. It replaces antigens but modifies the stimuli,” said Lu, leader of the study.

He said research into natural killer cells, T lymphocytes, begins after patients are diagnosed to have HIV and, during that time, the cells are kept in a cell culture and fed an artificial diet and protected from infection.
