Heavy chain-only antibodies with a stabilized human VH in transgenic chickens for therapeutic antibody discovery.

Heavy chain-only antibodies have found many applications where conventional heavy-light heterodimeric antibodies are not favorable. Heavy chain-only antibodies with their single antigen-binding domain offer the advantage of a smaller size and higher stability relative to conventional antibodies, and thus, the potential for novel targeting modalities. Domain antibodies have commonly been sourced from camelids with humanization or transgenic rodents expressing heavy chains without light chains, but these host species are all mammalian, limiting their capacity to elicit robust immune responses to conserved mammalian targets.

The results showed that seventeen of the twenty-eight derivatives have minimum inhibitory concentration (MIC) values lower than isoniazid (2.

Modulation of arterial intima stiffness by disturbed blood flow.

The intima, comprising the endothelium and the subendothelial matrix, plays a crucial role in atherosclerosis pathogenesis. The mechanical stress arising from disturbed blood flow (d-flow) and the stiffening of the arterial wall contributes to endothelial dysfunction. However, the specific impacts of these physical forces on the mechanical environment of the intima remain undetermined.

Exploring Genetic Silencing: RNAi and CRISPR-Cas Potential Against Drug Resistance in Malaria.

Malaria has been one of the most lethal infectious diseases throughout history, claiming a high number of human lives. The genomic plasticity of Plasmodium falciparum, the causative agent of the most severe and deadly form of malaria, gives the parasite a constant resistance to drugs developed for its control. Despite efforts to control and even eradicate the disease, these have largely been unsuccessful due to the parasite's continuous adaptations.

Small Molecule Therapeutics in the Pipeline Targeting for Triple-Negative Breast Cancer: Origin, Challenges, Opportunities, and Mechanisms of Action.

Triple-negative breast cancer (TNBC) cells are devoid of estrogen receptors (ERs), progesterone receptor (PRs), and human epidermal growth factor receptor 2 (HER2), and it (TNBC) counts for about 10-15% of all breast cancers.
