AMPs are exported from the cell after expression and translation. In the case of bacteria, the exported peptides target other microbes to give the producing bacterium a competitive edge. While AMPs are sought after for their similar antimicrobial activity to traditional antibiotics, it is difficult to predict which combinations of amino acids will confer antimicrobial activity. Many computer algorithms have been designed to predict whether a sequence of amino acids will exhibit antimicrobial activity, but the vast majority of validated AMPs in databases are still of eukaryotic origin.

Although the precise cause of PD is still unknown, various factors such as pesticide exposure, genetics, and lifestyle choices like smoking and caffeine consumption are thought to play a role in its development. The presence of Lewy bodies characterizes the disease, the aggregation of alpha-synuclein, the loss of dopaminergic neurons in the substantia nigra, and disruptions in basal ganglia circuitry, resulting in both motor and nonmotor symptoms. This review is structured into several key sections, beginning with an exploration of the pathophysiological mechanisms behind PD, including how genetic mutations can lead to deficits in the Ubiquitin Proteasome System and mitochondrial function, which are linked to familial cases of the disease. Following this, the article explores diagnostic methods, such as the UK Brain Bank Criteria, advanced imaging techniques, olfactory testing, and innovative technologies like machine learning, all of which support early detection and accurate diagnosis of PD. Treatment strategies are also comprehensively reviewed, focusing on traditional pharmacological options like levodopa and dopamine agonists, as well as surgical interventions such as deep brain stimulation. Additionally, the review discusses promising new therapies, including immunotherapy aimed at neuroinflammation and gene therapy for disease modification. The impact of lifestyle changes such as exercise and diet on reducing PD risk and enhancing symptom management are also considered.

Gene replacement therapy aims to restore the function of tumor suppressor genes, such as TP53, while gene silencing targets oncogenes like KRAS (Kirsten rat sarcoma viral oncogene homolog) to inhibit tumor growth.

This study explores the interplay between dopamine receptor subtypes (D1-D5) and associated genetic variations, particularly focusing on receptor heterodimers and polymorphisms influencing dopamine biosynthesis, signalling, and metabolism. A comprehensive review of molecular mechanisms highlights key findings: alterations in D1-D2 heterodimers contribute to mood dysregulation; D3 receptor downregulation correlates with depressive behaviour; and genetic polymorphisms, including those in tyrosine hydroxylase and dopamine transporter (DAT) genes, influence dopamine levels and receptor functions. Emerging data from neuroimaging and animal models confirm the pivotal role of dopamine receptor subtypes in MDD, offering insights into their therapeutic targeting. Here, we show that dopaminergic dysfunction underpins MDD's pathophysiology, with receptor-specific mechanisms presenting novel drug targets.
