Elongation of the linker region with parts of the mucin-like stalk of C[X.sub.3]CL1 and also deletion of domain II of PE reduced the efficacy of the FTPs in killing US28-expressing cells compared to F49A-FTP This is consistent with previous studies where eliminating the furin cleavage site by deletion or preventing cleavage with a point mutation in the sites reduced the cytotoxicity of a series of
immunotoxins [40].

Finally, we purified the
immunotoxin by nickel affinity chromatography and then verified the protein through SDS-PAGE (Figure 1(a)).
In addition, studies using immunosuppressant regimens along with the
immunotoxins also showed some benefit.[sup][3],[24],[25] Other regimens, including a lymphocyte-depleting regimen, which consists of pentostatin and cyclophosphamide, were also found promising in delaying the stimulation of neutralizing anti-immunotoxin antibodies, thus allowing repetitive
immunotoxin treatments for patients with solid tumors.[sup][25] Pentostatin and cyclophosphamide selectively suppress the effect of T- and B-cells while largely sparing myeloid cells.[sup][26]

According to the researchers, these findings, coupled with results from previous studies, suggest that treating certain HIV-infected people with a combination of antiretrovirals and an
immunotoxin might help achieve sustained disease remission, in which HIV can be controlled or eliminated without a lifetime of antiretroviral therapy.

Chapter 9 deals with the use of CD30 receptor as a target for
immunotoxin mediated therapy.
Inhibition of microglial activation after spinal injury reduces pain-related behaviors [44,91], and treatment with minocycline or the Mac-1-SAP
immunotoxin reverses morphological changes in microglia and attenuates functional and behavioral consequences of SCI.
