Compositions are disclosed that induce broadly HIV therapeutic and vaccine inducing antibodies against diverse HIV clades and relate to the ability to identify HIV gp120-derived short peptide sequence immunogens and various therapeutic compositions made from the identified peptides which compose CCR5 binding sites. Also disclosed are methods of selecting peptide sequences that are likely candidates for drugs which will offer effective treatment in such areas as Alzheimer's disease, psoriasis, multiple sclerosis and other diseases associated with the human inflammatory cascade as well as related retroviruses such as HTLV-1, the cause of tropical spastic paraparesis.
摘要:
A distal tip coupled to a body of an implantable medical device includes a canted passageway extending distally from a lumen of the body and an opening terminating the passageway and positioned in proximity to a distal end of the distal tip; a helical fixation element coupled to an elongated member extending within the lumen of the body is adapted to deflect along the canted passageway of the distal tip. The elongated member is adapted to move the helical member through the passageway of the distal tip and out from the opening and to rotate the helical element thereby affixing the helical element into an implant site.

Chemokine signaling is important in neuropathic pain, with microglial cells expressing CCR2 playing a well established key role. DAPTA, a gp120-derived CCR5 entry-inhibitor has been shown to inhibit CCR5-mediated monocyte migration and to attenuate neuroinflammation. We disclose here that as a stabilized analog of DAPTA, the short peptide All D TTNYT (SEQ ID NO:1) exhibits potent antagonism for both CCR2 (IC50 4.2 pM) and CCR5 (IC50 0.18 pM) in monocyte chemotaxis. Oral administration of All D TTNYT (SEQ ID NO:1) (0.05-1 mg/kg) for 7 days fully prevents mechanical allodynia and inhibits the development of thermal hyperalgesia following partial ligation of the sciatic nerve in rats. Administered from day 8 to day 12, All D TTNYT (SEQ ID NO:1) (0.2-1 mg/kg) reverses already established hypersensitivity. All D TTNYT (SEQ ID NO:1) relieves pain hypersensitivity probably through either or both CCR2 and CCR5, since by using genetically deficient animals, we demonstrated that in addition to CCR2, CCR5 is also required for the development of neuropathic pain. Moreover, All D TTNYT (SEQ ID NO:1) is able to reduce spinal microglial activation, monocyte infiltration, and to inhibit inflammatory responses evoked by peripheral nerve injury that cause chronic pain. Our findings suggests that the targeting CCR2/CCR5 should provide greater efficacy than targeting CCR2 or CCR5 alone and dual CCR2/CCR5 antagonist All D TTNYT (SEQ ID NO:1) has the potential for broad clinical use in neuropathic pain treatment.

摘要:
Residual HIV-1 replication reemerges after intensive therapy from location or locations in the body called the drug resistant non-plasma viral reservoir. Methods are disclosed of treating HIV by inhibiting or blocking this reemergence with various monomeric therapeutic peptide compositions including monomeric DAPTA prepared in least 80% trifluoroethanol, with vigorous shaking for at least about 24 hours at about 37° C.
摘要:
An assay to detect or quantify HIV infectious virus from clinically relevant cellular compartments, or reservoirs, in anti-retrovirally treated patients whose viral levels are low to undetectable is described. The method detects infectious virus in patients whose plasma viral loads are considered to be below the limit of current PCR based detection methods and thereby is more relevant for guiding treatment. A further advantage is that the method allows viral tropism to be directly determined in the presence of specific inhibitors of CCR5 or CXCR4. Drug sensitivity can also be directly determined without the need to laboriously recover patient virus by culture for extended time periods, a method that allows for viral selection or evolution, which is not desirable. Patient cells, like the blood mononuclear cells, or monocytes, are isolated and cultured in the presence of cytokines like CSF-1/M-CSF or GM-CSF. to promote their differentiation. Cells are activated with lectins, mitogenic antibodies, phorbol esters, Toll Receptor stimulation or inducers of NfKb or NFAT, followed by agents that induce viral release, like ATP or stimulation of autophagy with LiCl, spermidine, or rapamycin. A key aspect of the invention relates to the timing of the addition of these agents for optimal viral release. A further aspect of the invention relates to sensitive detection of released virus which can be accomplished by adding so-called reporter cells which are under control of the HIV TAT protein so that upon infection these cells synthesize proteins or enzymes that allow for the measurement of infectious particles.
