CTL are important in combating cancer and viruses. Therefore, triggering the complete potential of CTL effector functions by new vaccination strategies will not only improve prophylaxis of tumor or virus-related diseases, but also open opportunities for effective therapeutic immunizations. Using transcutaneous immunization, we show that epicutaneous (e.c.)(4) application of an ointment containing a CTL epitope and the TLR7 ligand imiquimod is highly effective in activating T cells in mice using TCR-transgenic CTL or in wild-type mice. Transcutaneous immunization-activated CTL mount a full-blown immune response against the target epitope characterized by proliferation, cytolytic activity, and the production of IFN-gamma that is completely restricted to the epitope used for vaccination. Our results obtained by simple e.c. application of an ointment, without further skin irritating procedures, provide the basis for the development of new, easy to use vaccines against cancer or virus-associated diseases.

Atopic dermatitis (AD) or eczema is an important inflammatory chronic skin disease that brings many complications in its management and treatment. Although several chemical agents are used for treatment, the search for better anti-inflammatory and antibacterial agents of plant origin has been ongoing, since natural compounds, it is commonly believed, are less dangerous than synthetic ones. Therefore, the present study explored a medicinal plant- (L.

Psoriasis is a chronic and incurable inflammatory skin disease usually requiring long-term disease management. Natural phytochemical resveratrol (RES) has been known for high efficiency and low toxicity, exhibiting good anti-psoriasis potential. However, its biological activity is limited by poor solubility, chemical instability, and insufficient skin retention.

The sustainable use of pomegranate peel, a by-product of the food industry, is gaining importance in developing pharmaceutical bio-inputs, aligning with circular economy practices and waste reduction. This study explores the application of dry crude pomegranate peel extract (PPE) as a bio-input for medicinal gels with wound healing properties. PPE was extracted via percolation in ethanol and freeze-dried.

Rationale: Steven-Johnson syndrome (SJS) is characterized by severe illness, rapid progression, and high mortality rates, with the vast majority of cases induced by medications. Botulinum toxin, a neurotoxin produced by Clostridium botulinum, has not been reported in the literature as a causative agent of SJS.
Patient Concerns: A 56-year-old male patient, who underwent surgery for cerebral hemorrhage, developed widespread patchy annular papules following the injection of botulinum toxin into the masseter muscle.
