Rituximab is a chimeric monoclonal antibody used in the treatment of some cancers like CD20 non-Hodgkin's lymphoma and a few autoimmune conditions such as rheumatoid arthritis. However, antibody treatment can lead to generation of neutralising antibodies thus curtailing the efficacy of the therapy. CD 4+ T cells are critical to initiate antibody response so identification of epitopes within molecules using T cell assays can be a vital tool for understanding the immune response and thereby prevent induction of neutralising antibodies. Within rituximab, the variable region of the light chain (41-55) was found to have strong affinity for leukocytes in a specific binding assay, the epitope was also correlated to patients who developed neutralising antibodies. This T cell epitope within rituximab in further immune studies could help design or selection of antibodies without T cell epitopes present for low immunogenicity.

Alyerserin-2b is a C-terminally α-amidated 17 residue cationic anti-microbial peptide (AMP). Anti-microbial peptides (AMPs) are produced by the innate immune system and are expressed when the host is challenged by a pathogen. The Alyerserin family of peptides was first identified in norepinephrine-stimulated skin secretions of the midwife toad-Alytes obstetricans-(Alytidae). Alyteserin-2a, 2b and -2c show some sequence identity with bombinin H6, a peptide from the skins Bombinatoridae family of frogs.Alyteserin-2b is most potent against the Gram-positive bacteria-Staphylococcus aureus and has weak haemolytic activity against human erythrocytes.Alyteserin contain at least 50% hydrophobic amino acids. Hydrophobic residues contribute to the insertion of the peptide into the hydrophobic membrane core which results in membrane disruption and death of the pathogen. Due to their mechanism of action it is thought to be less likely for resistance to develop towards them compared to conventional antibiotics. Alyteserin-2b has a low probability of adopting a helical conformation unlike related Alyteserin-2 peptides.
