Abstract
Immunohistochemistry is a powerful tool for studying neuronal tissue from humans at the molecular level. Obtaining fresh neuronal tissue from human organ donors is difficult and sometimes impossible. In anatomical body donations, neuronal tissue is dedicated to research purposes and because of its easier availability, it may be an alternative source for research. In this study, we harvested spinal cord from a single organ donor 2 h (h) postmortem and spinal cord from body donors 24, 48, and 72 h postmortem and tested how long after death, valid multi-color immunofluorescence or horseradish peroxidase (HRP) immunohistochemistry is possible. We used general and specific neuronal markers and glial markers for immunolabeling experiments. Here we showed that it is possible to visualize molecularly different neuronal elements with high precision in the body donor spinal cord 24 h postmortem and the quality of the image data was comparable to those from the fresh organ donor spinal cord. High-contrast multicolor images of the 24-h spinal cords allowed accurate automated quantification of different neuronal elements in the same sample. Although there was antibody-specific signal reduction over postmortem intervals, the signal quality for most antibodies was acceptable at 48 h but no longer at 72 h postmortem. In conclusion, our study has defined a postmortem time window of more than 24 h during which valid immunohistochemical information can be obtained from the body donor spinal cord. Due to the easier availability, neuronal tissue from body donors is an alternative source for basic and clinical research.

Diagnostics (Basel) 2022; 12:diagnostics12092114. [PMID: 36140515 PMCID: PMC9497899 DOI: 10.3390/diagnostics12092114] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 08/28/2022] [Accepted: 08/30/2022] [Indexed: 02/04/2023] Open
Abstract
The identification of a reliable and accurate post-mortem interval (PMI) is a major challenge in the field of forensic sciences and criminal investigation. Several laboratory techniques have recently been developed that offer a better contribution to the estimation of PMI, in addition to the traditional physical or physico-chemical (body cooling, lividity, radiocarbon dating, rigor mortis), chemical (autolysis), microbiological (putrefaction), entomological, as well as botanical parameters. Molecular biology (degradation pattern of macromolecules such as proteins, DNA, RNA), biochemical analysis of biological fluids (such as blood, cerebrospinal fluid, and vitreous humor), and immunohistochemistry are some of the most recent technological innovations. A systematic review of the literature was performed with the aim of presenting an up-to-date overview on the correlation between the immunohistochemical (IHC) expression of specific antigenic markers at different PMIs. The systematic review was performed according to PRISMA guidelines. Scopus and PubMed were used as search engines from January 1, 1998 to March 1, 2022 to evaluate the effectiveness of immunohistochemistry in estimating PMI. The following keywords were used: (immunohistochemical) OR (immunohistochemistry) AND (time since death) OR (post-mortem interval) OR (PMI). A total of 6571 articles were collected. Ultimately, 16 studies were included in this review. The results of this systematic review highlighted that IHC techniques, in association with traditional methods, add, in Bayesian terms, additional information to define a more accurate time of death and PMI. However, current IHC results are numerically limited and more data and studies are desirable in the near future.

Sakai K, Fukuda T, Iwadate K. Is the denervation or hyperinnervation of the cardiac sympathetic nerve in the subepicardium related to unexpected cardiac death? Cardiovasc Pathol 2014; 23:211-6. [PMID: 24795174 DOI: 10.1016/j.carpath.2014.03.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2014] [Revised: 03/11/2014] [Accepted: 03/21/2014] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Past studies have reported that abnormal innervation of cardiac sympathetic nerve can cause sudden cardiac death through the arrythmogenesis; however, the severe cardiac sympathetic degeneration does not necessarily cause clinical problems. This study aimed to examine whether denervation or hyperinnervation of cardiac sympathetic nerves in the subepicardium is associated with unexpected cardiac death (UCD). METHODS Cardiac tissues of 278 forensic autopsy cases within 48 h after death were analyzed by double-staining immunohistochemistry for tyrosine hydroxylase and neurofilament. The density of nerve fascicles and the degeneration rate in the subepicardium of the left ventricular anterior wall were compared between the UCD group and the non-UCD group. RESULTS The density of nerve fascicles was lower in the SCD group (median: 51.9/cm(2)) than in the non-SCD group (median: 58.9/cm(2)); however, the difference was not significant (P = .08). The degeneration rate was higher in the SCD group (median: 0.19) than in the non-SCD group (median: 0.17), but again, the difference was not significant (P = .43). The multiple logistic regression model did not show a significant association between the incidence of UCD and the density of nerve fascicles or the degeneration rate. CONCLUSIONS It cannot be concluded that the denervation or hyperinnervation of cardiac sympathetic nerves in the subepicardium is related to UCD. Abnormal innervation of cardiac sympathetic nerves in the subepicardium may not have a substantial effect on UCD, compared to other arrhythmogenic factors.

Abstract
In the last few years, cardiac sympathetic dysfunction in Parkinson disease (PD) has been postulated on the basis of decreased cardiac uptake of sympathoneural imaging tracers. However, the pathological substrate for the dysfunction remains to be established. We examined the left ventricular anterior wall from postmortem specimens with immunohistochemical staining for tyrosine hydroxylase (TH), neurofilament (NF) and S-100 protein in PD patients and control subjects, and quantified the immunoreactive areas. As TH-immunoreactive axons nearly disappeared and NF-immunoreactive axons drastically decreased in number, the morphological degeneration of the cardiac sympathetic nerves in PD was confirmed. Quantitative analysis showed that sympathetic nerves were preferentially involved. Triple immunofluorolabeling for NF, TH, and myelin basic protein showed clearly the profound involvement of sympathetic axons in PD. The extent of involvement of the cardiac sympathetic nerves seems likely to be equivalent to that in the central nervous system, including the nigrostriatal dopaminergic system. PD affects the cardiac sympathetic nervous system profoundly as well as nigrostriatal dopaminergic system.

Abstract
BACKGROUND Autonomic neuropathy and functional cardiac denervation are complications of diabetes mellitus (DM). It is unknown if DM patients show histopathologic evidence of cardiac denervation. METHODS AND RESULTS Nine sites were sampled at fixed distances from the atrioventricular valves from 27 postmortem hearts. Sections were stained with antibodies to S100 protein and to neurofilament (NF). Samples were visualized by light microscopy using the avidin-biotin peroxidase technique. The amount of cardiac nerves was graded blindly using semiquantitative methods according to the following criteria: Grade 0=presence of nerves in the epicardium only; Grade 1=strictly perivascular nerves; Grade 2=Grade 1 and nerve sprouts between myocardial cells sporadically; Grade 3=Grade 2 and nerve sprouts throughout the myocardium and endocardium. Specimens were divided into four groups. Control group consisted of patients with neither myocardial infarction (MI) nor DM. Experimental groups consisted of MI (n=7), MI with DM (n=6), and DM without MI (n=8). Average age of all patients was 57.3+/-15.7 years. No age differences existed among groups. Heterogeneous nerve distribution existed in all groups. S100-positive nerve density for control, MI, DM and MI, and DM without MI are 1.95+/-0.40, 1.66+/-0.54, 1.54+/-0.37, and 1.81+/-0.14, respectively (P=ns). NF-positive nerve density in the same groups were 1.10+/-0.18, 1.31+/-0.24, 1.13+/-0.12, and 1.19+/-0.42, respectively (P=ns). No differences in nerve densities between anterior and inferoposterior sections of the left ventricle existed. CONCLUSION In postmortem human hearts, cardiac nerve distribution was heterogeneous among normal, MI, and DM patients. No evidence of cardiac denervation in patients with DM was demonstrated.

Abstract
In order to study the changes in the pattern of autonomic innervation of the human cardiac conduction system in relation to age, the innervation of the conduction system of 24 human hearts (the age of the individuals ranged from newborn to 80 years), freshly obtained at autopsy, was evaluated by a combination of immunofluorescence and histochemical techniques. The pattern of distribution and density of nerves exhibiting immunoreactivity against protein gene product 9.5 (PGP), a general neural marker, dopamine beta-hydroxylase (DBH) and tyrosine hydroxylase (TH), indicators for presumptive sympathetic neural tissue, and those demonstrating positive acetylcholinesterase (AChE) activity, were studied. All these nerves showed a similar pattern of distribution and developmental changes. The density of innervation, assessed semiquantitatively, was highest in the sinus node, and exhibited a decreasing gradient through the atrioventricular node, penetrating and branching bundle, to the bundle branches. Other than a paucity of those showing AChE activity, nerves were present in substantial quantities in infancy. They then increased in density to a maximum in childhood, at which time the adult pattern was achieved and then gradually decreased in density in the elders to a level similar to or slightly less than that in infancy. In contrast, only scattered AChE-positive nerves were found in the sinus and atrioventricular nodes, but were absent from the bundle branches of the infant heart, whereas these conduction tissues themselves possessing a substantial amount of pseudocholinesterase. During maturation into adulthood, however, the conduction tissues gradually lost their content of pseudocholinesterase but acquired a rich supply of AChE-positive nerves, comparable in density to those of DBH and TH nerves. The decline in density of AChE-positive nerves in the conduction tissues in the elders was also similar to those of DBH and TH nerves. Our findings of initial sympathetic dominance in the neural supply to the human cardiac conduction system in infancy, and its gradual transition into a sympathetic and parasympathetic codominance in adulthood, correlate well with the physiologic alterations known to occur in cardiac rate during postnatal development. The finding of reduction in density of innervation of the conduction tissue with ageing is also in agreement with clinical and electrophysiological findings such as age-associated reduction in cardiac response to parasympathetic stimulation. Finally, our findings also support the hypothesis that, in addition to the para-arterial route, the parafascicular route of extension along the conduction tissue constitutes another pathway for the innervation of the conduction system of the human heart during development.

Abstract
BACKGROUND Sympathetic nerve activity is known to be important in ventricular arrhythmogenesis, but there is little information on the relation between the distribution of cardiac sympathetic nerves and the occurrence of spontaneous ventricular arrhythmias in humans. METHODS AND RESULTS We studied 53 native hearts of transplant recipients, 5 hearts obtained at autopsy of patients who died of noncardiac causes, and 7 ventricular tissues that had been surgically resected from the origin of ventricular tachycardia. The history was reviewed to determine the presence (group 1A) or absence (group 1B) of spontaneous ventricular arrhythmias. Immunocytochemical staining for S100 protein, neurofilament protein, tyrosine hydroxylase, and protein gene product 9.5 was performed to study the distribution and the density of sympathetic nerves. The average left ventricular ejection fraction was 0.22+/-0.07. A total of 30 patients had documented ventricular arrhythmias, including ventricular tachycardia and sudden cardiac death. A regional increase in sympathetic nerves was observed around the diseased myocardium and blood vessels in all 30 hearts. The density of nerve fibers as determined morphometrically was significantly higher in group 1A patients (total nerve number 19.6+/-11.2/mm(2), total nerve length 3.3+/-3.0 mm/mm(2)) than in group 1B patients (total nerve number 13.5+/-6.1/mm(2), total nerve length 2.0+/-1.1 mm/mm(2), P<0. 05 and P<0.01, respectively). CONCLUSIONS There is an association between a history of spontaneous ventricular arrhythmia and an increased density of sympathetic nerves in patients with severe heart failure. These findings suggest that abnormally increased postinjury sympathetic nerve density may be in part responsible for the occurrence of ventricular arrhythmia and sudden cardiac death in these patients.

Abstract
BACKGROUND Cardiac ganglia were originally thought to contain only cholinergic neurons relaying parasympathetic information from preganglionic brain stem neurons to the heart. Accumulating evidence, however, suggests that cardiac ganglia contain a heterogeneous population of neurons that synthesize or respond to several different neurotransmitters and neuropeptides. Reports regarding monoamine and histamine synthesis and neurotransmission within cardiac ganglia, however, present conflicting information or are limited in number. Furthermore, very few studies have examined the neurochemistry of adult human cardiac ganglia. The purpose of this study was, therefore, to determine whether monoamine- and histamine-synthesizing enzymes and neurotransmitters exist within neurons of adult human cardiac ganglia. METHODS AND RESULTS Human heart tissue containing cardiac ganglia was obtained during autopsies of patients without cardiovascular pathology. Avidin-biotin complex immunohistochemistry was used to demonstrate tyrosine hydroxylase, L-dopa decarboxylase, dopamine beta-hydroxylase, phenylethanolamine-N-methyltransferase, tryptophan hydroxylase, and histidine decarboxylase immunoreactivity within neurons of cardiac ganglia. Dopamine, norepinephrine, serotonin, and histamine immunoreactivity was also found in ganglionic neurons. Omission or preadsorption of primary antibodies from the antisera and subsequent incubation with cardiac ganglia abolished specific staining in all cases examined. CONCLUSIONS Our results suggest that neurons within cardiac ganglia contain enzymes involved in the synthesis of monoamines and histamine and that they contain dopamine, norepinephrine, serotonin, and histamine immunoreactivity. Our findings suggest a putative role for monoamine and histamine neurotransmission within adult human cardiac ganglia. Additional, functional evidence will be necessary to evaluate what the physiological role of monoamines and histamine may be in neural control of the adult human heart.
