Final, sorry: Similarities Between The Heart And The Human

Toxicological research requires animal models that are physiologically closely related to one another.

There is good evidence that non-human primates NHPsincluding rhesus and cynomolgus monkeys Macaca fascicularisclosely Humman these requirements at both the molecular and developmental levels 1. However, the recently failed first-in-human clinical trial of TGN theralizumab raises concerns about whether the immune system of NHPs can be used to predict how TGN affects in humans.

In Simillarities trial, six healthy volunteers suffered severe adverse events soon after TGN antibody administration, while preclinical safety testing in cynomolgus monkeys had suggested that TGN could be tolerated without toxicity 23. It has been suggested that the immune response to exogenous substances differs between these two species.

Expert Answer

Therefore, comparative studies of the immune system, especially the functional differences of immune cells, in humans and NHPs, could provide valuable information for better extrapolating animal toxicity data in preclinical drug safety studies using NHPs. The immune system is highly complex and Anx of lifelong renewal. The normal physiological range of variation in the immune system is affected by age, sex, environment, and other factors; this diversity presents a major challenge in assessing drug-induced immunotoxicity 45. However, research on the anatomical and functional differences between the immune systems of monkeys and humans has been limited.

Furthermore, the information obtained from human and NHPs can facilitate the comparative study of different species under the same treatment conditions 89. In addition to classical immune cells function trials, microarrays can be a valuable tool for translating data from animals to humans 10 - Comparing differences between the expression profiles of genes associated with toxicity among various animal and human tissues to identify the significant key genes expressed in each type of host would provide a better translation of animal toxicity data to human scenarios 14 Thus, our aim was to compare the Similarities Between The Heart And The Human in cell proliferation, cytokine secretion, and gene profiles of human and cynomolgus monkey PBMCs under various stimulations in vitro, to provide new specific primate data for comparative immunology. LPS is a part of the outermost layer of Gram-negative bacteria, https://amazonia.fiocruz.br/scdp/essay/calculus-on-manifolds-amazon/should-school-employees-should-not-carry-guns.php is used to study the innate immune response after bacterial infection in vitro by pathogen-associated molecular pattern PAMP.

PHA can activate small lymphocytes to transform into lymphoblasts, then divide and proliferate, release cytokines, and improve the phagocytic ability of macrophages.

PHA binds to specific cell surface carbohydrates on T-cells and is often used in immunology studies as a T-lymphocyte proliferation inducer.]
