Accurately classifying the innate immune players is essential to comprehensively and quantitatively evaluate the interactions between the innate and the adaptive immune systems. In addition, accurate classification enables the development of models to predict behavior and to improve prospects for therapeutic manipulation of inflammatory diseases and cancer. Rapid development in technologies that provide an accurate definition of the type of cell in action, allows the field of innate immunity to the lead in therapy developments. This article presents a novel immunophenotyping technique using electrical characterization to differentiate between the two most important cell types of the innate immune system: dendritic cells (DCs) and macrophages (MACs). The electrical characterization is based on capacitance measurements, which is a reliable marker for cell surface area and hence cell size. We differentiated THP-1 cells into DCs and MACs in vitro and conducted electrical measurements on...

Camel and human milk samples (twenty individuals’ samples each) were analysed for fat, total protein (casein, whey protein), lactose, minerals as well as vitamins; B1, B2, niacin and C. Meanwhile, amino and fatty acid compositions and, antimicrobial factors namely; lysozyme (LZ), lactoferrin (LF) and total immunoglobulins (Igs) were determined. Results indicated that camel milk contained higher fat, protein (especially casein), ash, Ca, Mg, P, K, Na, Fe, and Cu but lower in whey protein, lactose and Zn than human milk. Vitamins C and niacin were higher in camel milk than human milk. Camel milk proteins contained satisfactory balance of essential amino acids. The ratio of essential to non-essential amino acids was 0.93 and 1.07 in camel and human milk proteins, respectively. Camel milk was characterized by higher ratio of Igs but lower in both LZ and LF than human milk. General pattern of camel milk fatty acids indicated that short chain fatty acids (C4 –C12) were present in very sma...
