A composition comprising a molecular blockade agent to a costimulatory molecule which costimulatory molecule satisfies the following criteria: a. absent in naÊve or resting T-lymphocytes; b. inducible; c. expressed; and d. prominent at the height of an immunopathological response, such as a disease/condition response. Preferably, the costimulatory molecule is OX40 and the molecular blockade agent is an antibody or antibody fragment having antibody activity to OX40. Further, the system may involve modulation of the molecular signal pathway of the aforesaid costimulatory molecule.
