The spectrum of diseases caused by intracellular bacterial pathogens (IBPs) is broad, ranging from life-threatening conditions such as tuberculosis to other infectious-transmitted diseases. Conventional antibiotic treatment faces challenges due to antibiotic resistance, host cell toxicity, and limited drug penetration. Despite the excellent ability of these perilous pathogens to modulate host cell biology, localize in, and multiply through targeting the key virulence factors, cell brings about auspicious maneuvers to combat pathogenic diseases and alleviate their significant global burden. Modulation and identification of molecules, pathways, and responses are the initial steps of targeted therapy, varying from disease to disease. This article explores the cutting-edge advancements in targeted therapy approaches. Innovations such as nanoparticlebased drug delivery systems, phage therapy, immunomodulation, and gene editing, which hold a promising future for overcoming the limitations of traditional treatment, are also discussed. Efficient delivery systems, drug optimizations, and inch-perfect distribution and retention of therapeutic agents are some of the determining factors in the success of targeted therapy for bacterial pathogens. The article also presents a novel application wherein filamentous phages are loaded as targets in nanocarriers for therapeutic purposes. The present challenges faced by the researchers, along with future directions for this field of medical science, are also outlined. Overall, the scope of this article involves the various strategies involved in targeted therapy, drug modulations, and limitations faced in our current approaches.

A growing body of evidence suggests that inflammation may play a role in unstable angina and acute myocardial infarction. Neutrophil activation has been demonstrated in unstable angina and acute myocardial infarction. Myeloperoxidase is the major constituent of primary azurophil granules is neutrophil and discharged after activation. The chart of thirty-two patients (female 19 male 13) who were admitted in coronary care unit because of myocardial infarction and unstable angina pectoris were selected. Myeloperoxidase content (MPxI) had been determined using H1 hematology analyzer. In normal subjects this index is about 0 and negative values appear when the neutrophil are depleted of myeloperoxidase, which typically happens after neutrophil activation. Risk factors such as current smoking, hypertension, diabetes mellitus and high cholesterol level were recorded. The mean age of patients was 65 years old (female 66 male 64) with a range of 29 to 91. Leukocytosis and neutrophilia were present in 13 (40%) and 16 (50%) respectively. The range of ESR was between 1 to 28 (millimeter/hours) with mean = 10.4. The mean of MPxI was -3.04 (female -4.5 male -1.3, P=0.27). MPxI in patients who had positive and negative history of chronic stable angina was -5.14 and -2.3 (P=0.64) respectively. Because most of the patients had two or more risk factors, the relation between risk factors and MPxI, independently, was not possible to evaluate. There was no correlation between amount of creatin phosphokinase rising and age with MPxI values. During myocardial ischemia, neutrophil activity is increased. Further study is needed for determination whether neutrophil activation is caused by myocardial event or whether it is an independent, primary event.

Background: Endometriosis is a complex disease that profoundly affects the quality of life in many women. This disease affects roughly one in ten women of reproductive age. Endometriosis induces a variable amount of inflammatory reaction in pelvic environment. An active immune system needs to recognize these inflammatory agents. Rapid innate immune system defenses against infections involve the recognition of invading viral and bacterial pathogens, by the family of Toll like receptors (TLRs). Among TLRs family only TLR3, 7, 8 and 9 that expressed in the intracellular endosomal compartments, which can detect viral infections.TLR3 distinguishes double strand RNA viral motifs. TLR 7/8 are specific for single strand RNA. While TLR9 recognizes unmethylated CPG DNA of viruses. The objective of this study is to clarify the expression of intracellular TLRs in the woman with endometriosis.Materials and Methods: In this study three groups were examined. Ectopic biopsies were obtained with laparoscopic procedure from patient with endometriosis. Eutopic and control biopsies were gained with piplle from endometrium of women with and without endometriosis.Reverse transcriptase polymerase chain reaction (RTPCR) and quantitative-PCR (Q-PCR) for 5 samples of each groups used to show the existence of TLR3, 7, 8 and 9 genes.Results: TLR3, 7, 8 and 9 mRNA were expressed in the each groups but in ectopic and eutopic samples we showed variable expression.Conclusion: Our finding suggested that TLRs is involved in endometriosis pathophysiology. It is shown that some products of TLRs signaling such as TNf-a and IL-1 were increased in endometriosis.
