Iron deficiency anemia (IDA) is one of the most common complications of inflammatory bowel disease (IBD). We planned a prospective study to address tolerability and efficacy of sucrosomial iron, a new oral formulation of ferric pyrophosphate, in IBD patients. Thirty patients with a confirmed diagnosis of Crohn’s Disease (CD) or ulcerative colitis (UC) and mild IDA were enrolled. Patients with severe...
Cytotoxic T cell responses are key to the control of intracellular pathogens including HIV-1. In particular, HIV-1 vaccines based on regulatory proteins, such as Tat, are aimed at controlling HIV-1 replication and at blocking disease development by inducing cytotoxic T cell responses. Naked DNA is capable of inducing such responses but it requires several inoculations of high amounts of DNA, and/or...
A novel class of cationic block copolymers constituted by a neutral hydrophilic poly(ethylene glycol) (PEG) block and a positively charged poly(dimethylamino)ethyl methacrylate block was prepared for delivery of DNA. These block copolymers spontaneously assemble with DNA to give in aqueous medium micellar-like structures. Five of these novel block copolymers (K1-5), differing in the length of both...
Previous work from our group showed that genetic immunization of mice with HIV-1 tat genes (tat 22 and tat 22/37 ), encoding Tat proteins mutated in the transactivation domain and lacking Tat-transactivating activity, evoke an immune response to wild-type Tat, both humoral and cellular. In the present work we report that the mutated Tat proteins localize within...
