INFECTIOUS DISEASE EXPERTS RECOMMEND USING ANTIBODIES FROM COVID-19 SURVIVORS AS STOPGAP MEASURE TO TREAT PATIENTS AND PROTECT HEALTH CARE WORKERS

Countries fighting outbreaks of the novel coronavirus disease COVID-19 should consider using the antibodies of people who have recovered from infection to treat cases and provide short-term immunity—lasting weeks to months—to critical health care workers, argue two infectious disease experts.

Designer Probiotic Treatment for Cancer Immunotherapy

Columbia Engineers have engineered probiotics to safely deliver immunotherapies within tumors, including nanobodies against two proven therapeutic targets—PD-L1 and CTLA-4. Continuously released by bacteria, the drugs continue to attack the tumor after just one dose, facilitating an immune response resulting in tumor regression. The versatile probiotic platform can also be used to deliver multiple immunotherapies simultaneously, enabling the release of effective therapeutic combinations within the tumor for more difficult-to-treat cancers like colorectal cancer.

High-Tech Printing May Help Eliminate Painful Shots

Painful hypodermic needles may not be needed in the future to give shots, inject drugs and get blood samples. With 4D printing, Rutgers engineers have created tiny needles that mimic parasites that attach to skin and could replace hypodermic needles, according to a study in the journal Advanced Functional Materials.
