Abstract
Cationic antimicrobial peptides are observed throughout nature. In mammals they are observed both at epithelial surfaces and within the granules of phagocytic cells. They are an important component of innate defences, since in addition to their ability to kill microorganisms, they are able to modulate inflammatory responses. With respect to their ability to kill bacteria, it is very difficult to isolate resistant mutants. However there are a few known mechanisms of intrinsic resistance, including PhoPQ-dependent and other alterations in lipopolysaccharide structure that influence self promoted uptake, and protease-mediated resistance.

"Tuberculosis Prevention, Diagnosis and Drug Discovery"
The Nobel Prize-winning discoveries of Mycobacterium tuberculosis and streptomycin have enabled an appropriate diagnosis and an effective treatment of tuberculosis (TB). Since then, many newer diagnosis methods and drugs have been saving millions of lives. Despite advances in the past, TB is still a leading cause of infectious disease mortality ...read more
Current Pharmaceutical challenges in the treatment and diagnosis of neurological dysfunctions
Neurological dysfunctions (MND, ALS, MS, PD, AD, HD, ALS, Autism, OCD etc..) present significant challenges in both diagnosis and treatment, often necessitating innovative approaches and therapeutic interventions.

Emerging and re-emerging diseases
Faced with a possible endemic situation of COVID-19, the world has experienced two important phenomena, the emergence of new infectious diseases and/or the resurgence of previously eradicated infectious diseases. Furthermore, the geographic distribution of such diseases has also undergone changes. This context, in turn, may have a strong relationship with ...read more
