Cell-Free Treatments: A New Generation of Targeted Therapies for Treatment of Ischemic Heart Disease.

Although recent progress in medicine has substantially reduced cardiovascular diseases (CVDs)-related mortalities, current therapeutics have failed miserably to be beneficial for all patients with CVDs. A wide array of evidence suggests that newly-introduced cell-free treatments (CFTs) have more reliable results in the improvement of cardiac function. The main regeneration activity of CFTs protocols is based on bypassing cells and using paracrine factors.

47D11 Antibody-Engineered Exosomes for Targeted Delivery of Remdesivir in Patients with COVID-19: Dream or Principle? (A Critical Editorial Study).

Along with the high transmission rate of coronavirus disease 2019 infection in the last few months, the morbidity and mortality rate of coronavirus disease 2019 has been increased among critically-ill patients, especially the elderly or the ones with immunodeficiencies. So, there is an urgent need to develop more effective therapeutic agents through immunopathophysiological and immunotherapeutic-based strategies for these patients. Here, we hypothesize that mixing S1b-RBD-expressing mesenchymal stem cell-derived exosomes (which have been previously enriched with Remdesivir) with 47D11 antibody, can promisingly guarantee effective transferring of those targeted exosomes to the targeted microenvironment of coronavirus disease 2019 infection.
