Listeriolysin O (aka LLO) is a hemolysin produced by Listeria monocytogenes bacteria, the pathogen responsible for causing listeriosis. The toxin may be regarded as a virulence factor, since it is crucial for the virulence of L. monocytogenes. LLO is a single polypeptide protein encoded by the hlyA gene and composed of 529 residues. LLO is a thiol-activated cholesterol-dependent pore forming toxin protein; therefore, it is activated by reducing agents and inhibited by oxidizing agents. Still, LLO differs from other thiol-activated toxins, as its cytolytic activity is maximized at a pH of 5.5. Inside the acidic phagosomes (average pH ~ 5.9) of cells that have phagocytosed L. monocytogenes, LLO is selectively activated by maximizing activity at a pH of 5.5. Following the phagosome lysis by LLO, the bacterium breaks out into the cytosol, where it is able to grow intracellularly, and the toxin has reduced activity in the more basic cytosol. Thus, LLO permits L. monocytogenes to break out from the phagosomes into the cytosol without harming the plasma membrane of the infected cell, which allows the bacteria to live intracellularly, where they are sheltered from extracellular immune system factors such as the complement system and antibodies.

Coagulation factor VIII participates in the intrinsic pathway of blood coagulation; factor VIII is a cofactor for factor IXa which, in the presence of Ca+2 and phospholipids, converts factor X to the activated form Xa. This gene produces two alternatively spliced transcripts. Transcript variant 1 encodes a large glycoprotein, isoform a, which circulates in plasma and associates with von Willebrand factor in a noncovalent complex. This protein undergoes multiple cleavage events. Transcript variant 2 encodes a putative small protein, isoform b, which consists primarily of the phospholipid binding domain of factor VIIIc. This binding domain is essential for coagulant activity. Defects in this gene results in hemophilia A, a common recessive X-linked coagulation disorder.

Nesfatin-1 was first described in 2006 as a neurohormone derived from the protein NEFA/nucleobindin2 (NUCB2). It is a polypeptide consisting of 82 amino acids, with high level of homology in human, mouse and rat. Nesfatin-1 has been localized in the brain, particulary in the nuclei of the hypothalamus, in the adipose tissue and the gastrointestinal tract, but also in serum and cerebrospinal fluid. Nesfatin-1 was identified as a satiety molecule affecting fat metabolism. Intracerebroventricular administration of nesfatin-1 induces decreases in food intake and body weight and increases in sympathetic nerve activity and mean arterial pressure. Effect of Nesfatin-1 is leptin – independent, it is probably mediated by melanocortin system. Several studies are currently focused on the possibility of using Nesfatin-1 in the treatment of obesity, even in individuals with leptin resistence. Due to the presence in serum Nesfatin-1 could also serve as a clinical marker in the diagnosis of many diseases.
