Immune Response Following Quadrivalent Human Papillomavirus Vaccination in Women After Hematopoietic Allogeneic Stem Cell Transplant: A Nonrandomized Clinical Trial.

Importance: Human papillomavirus (HPV) infection is found in about 40% of women who survive allogeneic hematopoietic stem cell transplant and can induce subsequent neoplasms.

Objective: To determine the safety and immunogenicity of the quadrivalent HPV vaccine (HPV-6, -11, -16, and -18) in clinically stable women post-allogeneic transplant compared with female healthy volunteers.

Interventions: Participants received the quadrivalent HPV vaccine in intramuscular injections on days 1 and 2 and then 6 months later.

A Practical Guide to Gynecologic and Reproductive Health in Women Undergoing Hematopoietic Stem Cell Transplant.

Optimum care of female transplant recipients requires gynecologic care at several stages through the allogeneic hematopoietic stem cell transplantation (HCT) process. Sex-based considerations in women post-HCT span gynecologic sequelae of transplant along with assessment and maintenance of optimal sexual and gynecologic health. Pre-HCT, managing menstruation and abnormal uterine or genital bleeding, considering fertility preservation, and assessing for sexually transmitted infections, including human papillomavirus (HPV)-related disease and cervical cancer, enhance women's health.

Anthrax toxin-mediated delivery of the Pseudomonas exotoxin A enzymatic domain to the cytosol of tumor cells via cleavable ubiquitin fusions.

Unlabelled: Anthrax toxin proteins from Bacillus anthracis constitute a highly efficient system for delivering cytotoxic enzymes to the cytosol of tumor cells. However, exogenous proteins delivered to the cytosol of cells are subject to ubiquitination on lysines and proteasomal degradation, which limit their potency. We created fusion proteins containing modified ubiquitins with their C-terminal regions fused to the Pseudomonas exotoxin A catalytic domain (PEIII) in order to achieve delivery and release of PEIII to the cytosol.

Recombinant expression and purification of a tumor-targeted toxin in Bacillus anthracis.

Many recombinant therapeutic proteins are purified from Escherichia coli. While expression in E. coli is easily achieved, some disadvantages such as protein aggregation, formation of inclusion bodies, and contamination of purified proteins with the lipopolysaccharides arise.
