A method of treatment of pain in a person with a D peptide chemokine receptor antagonist (CRA), and a pharmaceutically acceptable carrier is disclosed. Because chemokines desensitize opiate receptors and enhance the perception of pain said D-peptide CRA, given with a suboptimal dose of an opioid, such as morphine, will restore opioid analgesic efficacy by blocking the cognate chemokine ligand from binding to its receptor and desensitizing the opioid receptor. This strategy of combining a suboptimal dose of morphine with a CRA enhances the potency of morphine, permitting use of lower doses of morphine to obtain equivalent and near maximal analgesia. Lower morphine (opioid) doses have less risk of adverse effects, and potentially also of development of tolerance and dependence.

Use of an all-D-pentapeptide chemokine antagonist to reduce opioid dose in a person with pain

A method of treating a person with a substance abuse disorder, in particular, opioid abuse and psychostimulant abuse with a chemokine receptor antagonist pharmaceutical composition, is provided herein. An antagonist comprising five contiguous amino acids having the general structure: A-B-C-D-E in which A is Ser, Thr, Asn, Glu, or Ile; B is Ser, Thr, Asp, or Asn; C is Thr, Ser, Asn, Arg, or Trp; D is Tyr and E is Thr, Ser, Arg, or Gly, is provided herein. The stereoisomeric amino acids are D stereoisomers. The method both relieves a person's symptoms and reduces the person's risks of addiction.

Compositions are disclosed that induce broadly HIV theraputic 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.

Therapeutic peptides and vaccines

A method of treating liver inflammation in an individual caused by excess fat deposition, sometimes called 'fatty liver disease', which may be caused by metabolic syndrome, insulin resistance, or gut microbial dysbiosis, and which may lead to the serious and potentially life-threatening condition of non-alcoholic steatohepatitis (NASH). A composition composed of an all-D amino acid peptide and a pharmaceutically acceptable carrier is prepared and administered to a patient. The D peptide has the general structure: A-B-C-D-E in which The composition acts to suppress inflammation underlying steatohepatitis. The D peptide may be esterified, glycosylated, or amidated at E to enhance tissue distribution by promoting egress from the circulation and penetration into the liver.

Uses of peptides to treat brain injury and disease

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 (IC4.2 pM) and CCR5 (IC0.18 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.

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&#xb0; C.

The present invention relates to alkylglycoside-containing compositions and methods for increasing the stability, reducing the aggregation and immunogenicity, increasing the biological activity, and reducing or preventing fibrillar formation of a peptide, polypeptide, or variant thereof, for example insulin and Peptide T or analog thereof.

Peptide pharmaceutical compositions

The HIV-1 envelope protein gp120 is toxic to rodent and human neurons by indirect mechanisms requiring accessory glial cells. Chemokines are known to block gp120 interactions with chemokine receptors on T cells, macrophanges, and microglia, thereby preventing viral infection. Gp120-induced neuronal killing in rat hippocampal cultures was partially or completely prevented by a specific short peptides related to chemokines, specially IKEYFTS (SEQ. ID NO: 2) and LESYT (SEQ. ID NO: 1). These peptides thus have use in the treatment of neurological degenerative diseases having symptoms associated with neuronal cell death.
