Our data also showed that neither cell morphology and MTT assay, nor the T4 cell counts were sufficient to predict correctly the fate of these exposures as it relates to the death endpoints for these cell lines.
That scientific consensus is likely to pressure FDA to put more weight on a drug's ability to boost T4 cell levels in evaluating AIDS drugs in the future.
The results of the T4 cell analysis showed statistically significant differences (p < 0.
When the virus kills a T4 cell, the cell secretes something that kills other cells around it, his laboratory has found.
When T4 cells were injected into nude mice given arsenite-containing water from 1 week before injection until the end of the experiment, the number of tumors formed and the rate of tumor formation were the same as in similarly injected nude mice given arsenite-free water (data not shown), showing that the continued presence of arsenite did not enhance tumor progression.
The T4 cells in turn stimulate antibody production by B lymphocytes.
The promising results were gleaned from only about 1,300 of the study's 3,200 subjects--those whose immune system was at least moderately impaired, as shown by a depressed level of T4 cells (special immune cells) -- 200 to 500 per cubic millimeter of blood.
NYSE:ENZ), in a presentation at the annual meeting of the American Society of Gene Therapy here, reported the continued expression of anti-HIV antisense RNA in T4 cells in the follow-up phase of the Company's clinical trial.
When the panel scientists looked at data collected on 1,300 participants who had fewer than 500 T4 cells upon entering the study, they found that people on zidovudine were about half as likely as those on placebo to develop symptoms of ARC or AIDS after one year in the study.
Within hours of infection there are enough infected T4 cells in the blood for BFTI's test to detect, unlike the weeks to even years required by conventional tests that rely on antibody production.
The new research indicates that AIDS patients harbor HIV in more than one of every 100 CD4-positive T4 cells -- the white blood cells that serve as the major target and reservoir of HIV.
CoQ10, a naturally occurring substance with low toxicity, is a potent immune stimulant with antioxidant properties that has been shown to prevent tissue damage and stimulate the immune system by increasing the number of healthy circulating T4 cells.
