Målvävnadsselektiv

Målvävnadsselektiv, a Swedish term, translates to "target tissue selective" in English. It describes a substance or treatment that preferentially affects or acts upon a specific type of tissue within the body. This selectivity is crucial in many areas of medicine and biology, particularly in pharmacology and drug development.

When a drug is described as målvävnadsselektiv, it means the drug molecules are designed to interact primarily with receptors or biological pathways found in the intended target tissue. This minimizes interactions with other tissues, thereby reducing the likelihood of off-target effects and associated side effects. For example, a chemotherapy drug might be designed to be målvävnadsselektiv for rapidly dividing cancer cells, sparing healthy tissues as much as possible.

The development of målvävnadsselektiva agents involves understanding the unique molecular characteristics of the target tissue. This can include identifying specific cell surface receptors, intracellular enzymes, or gene expression patterns. Once these targets are identified, researchers can design molecules that bind with high affinity and specificity to these targets.

In gene therapy, the term can also refer to the delivery of genetic material to specific tissues. Viral vectors or other delivery systems are engineered to target particular cell types, ensuring that the therapeutic gene is expressed only where it is needed. This precise targeting is essential for both efficacy and safety in gene-based treatments. The principle of målvävnadsselektivitet is a cornerstone of modern, precision-based approaches to healthcare.
