Analysis of Mannose‐Binding Lectin Protein and mRNA Levels on Selected Chicken Breeds in South Africa by Peter Ayodeji Idowu, Takalani J. Mpofu, Oliver T. Zishiri, Khathutshelo A. Nephawe, Bohani Mtileni

“…ABSTRACT Background Mannose‐binding lectin (MBL) is a key component of the innate immune system that plays a crucial role in binding to the microbial sugar surface to recognize and eliminate pathogens by activating the complement system. Objective To detect and quantify the MBL protein concentration and chicken MBL expression in selected chicken breeds in South Africa. …”

The AMD-associated genetic polymorphism CFH Y402H confers vulnerability to Hydroquinone-induced stress in iPSC-RPE cells by Angela Armento, Inga Sonntag, Ana-Cristina Almansa-Garcia, Merve Sen, Sylvia Bolz, Blanca Arango-Gonzalez, Ellen Kilger, Ruchi Sharma, Kapil Bharti, Rosario Fernandez-Godino, Berta de la Cerda, Simon J. Clark, Simon J. Clark, Simon J. Clark, Marius Ueffing

“…One of the main genetic risks includes the Y402H polymorphism in complement Factor H (FH), an inhibitor of complement system activation. There has been, and continues to be, much discussion around the functional consequences of this Y402H polymorphism, whether the soluble FH protein confers its risk association, or if the cells expressing the protein themselves are affected by the genetic alteration. …”
