Newly found sensing system enables certain bacteria to resist human immune defenses

... this system they could develop new drugs that are more effective at protecting people from infection. Likewise, now Dr. Otto and his research group are hoping for similar possibilities for gram-positive bacteria with their discovery of “aps,” which stands for antimicrobial peptide sensor. Aps has thre...

Research shows cord blood comparable to matched bone marrow

...w.” The research suggests that it will become more important to invest in cord blood banks that meet certain standards in relation to cell dose (or volume of the transplanted cells) and Human Leukocyte Antigen (HLA) diversity. Human Leukocyte Antigens (HLA) are a group of proteins on bone marrow c...

This limitation might be overcome by imp...
