Combat Viral and Bacterial Infections with Targeted Immune Cells

Dendritic cell molecules within the body’s immune system can be modified to improve our ability to combat viral and bacterial infections. 

The body’s immune system is designed to protect it from invading organisms and other pathogens. However, the immune system alone may not always be able to combat viral and bacterial infections, and antimicrobial therapies are implemented. A different approach would be to manipulate or affect immune system cells to control infections. Researchers at the Scripps Research Institute, La Jolla, CA have discovered that immune system molecules exist that can make people more vulnerable to bacterial infections, and that modifying expression or function of these immune molecules can enhance resistance to detrimental bacterial infections.

PBMCs and Psoriasis Treatments

Scientists examined the peripheral blood mononuclear cell (PBMC) profiles of patients with and without psoriasis, including those that both responded to classic treatments and didn’t respond. They then analyzed the profile of those immune cell types. Here are the results of that study.

There are often differences among patient populations for a given disease in how effective a treatment provides medical relief. An important part of personalized medicine is identifying patients that are not likely to respond to a treatment regimen for a specific disease or condition. Doing this can limit the loss of time and resources in using ineffective treatments and can allow the use of personalized treatments in these populations.

Stem Cell-Like Function of Adult Immune Cells Stimulate Healing

Apr 9, 2018 10:05:00 AM / by Stacy Matthews Branch, DVM, PhD posted in macrophages, stem cells, immune cells

New research suggests that wound fluid induced macrophage clustering shows improved healing.

Tissue damage is repaired by the proliferation of normal cells, tissue stem cell maturation, and scar formation. However, the inflammation associated with tissue damage or injury promotes cell plasticity as part of the tissue repair process. Fibroblasts that are critical for wound healing are mesenchymal cells that are actually derived from myeloid cells such as macrophages. Macrophages are immune cells that are the first line of defense against pathogens. They are also important in wound healing and inflammatory processes.
